Lead (Pb) Free Product - RoHS Compliant Red SLR2016 Super-red SLO2016 Green SLG2016 Yellow SLY2016 X/Y Stackable 0.180’’ 4-Digit 5x7 Dot Matrix Alphanumeric Intelligent Display® Devices with Memory/Decoder/Driver 2006-01-23 1

DESCRIPTION

The SLR/SLO/SLG/SL Y2016 is a four digit 5 x 7 dot matrix display module with a built-in CMOS integrated circuit. This display is X/Y stackable. The integrated circuit contains memory, a 128 ASCII ROM decoder, multiplexing circuitry and driv- ers. Data entry is asynchronous. A display system can be built using any number of SLR/SLO/SLG/SL Y2016 since each digit can be addressed independently and will con- tinue to display the character last stored until replaced by another. System interconnection is very straightforward. Two address bits (A0, A1) are normally connected to the like-named inputs of all displays in the system. Data lines are connected to all SLR/SLO/SLG/SL Y2016s directly and in parallel as is the write line ( WR). The dis- play will then behave as a write-only memory. The SLR/SLO/SLG/SL Y2016 has several features supe- rior to competitive devices. 100% burn-in processing insures that the SLR/SLO/SLG/SL Y2016 will function in more stressful assembly and use environments. True “blanking” allows the designer to dim the display for more flexibility of display presentation. Finally the CLR clear function will clear the ASCII character RAM. The character set consists of 128 special ASCII charac- ters for English, German, Italian, Swedish, Danish, and Norwegian. All products are 100% burned-in and tested, then subjected to out-going AQL ’s of 0.25% for brightness matching, visual alignment and dimensions, 0.065% for electrical and functional.

Data entry may be asynchronous. Digit 0 is defined as right hand digit with A1=A2=0. Clearing the entire internal four-digit memory can be accomplished by holding the clear (CLR) low for 1.0 msec minimum. The clear function will clear the ASCII RAM. Loading an illegal data code will display a blank. Pin Function Pin Function Pin Function

SLR2016, SLO2016, SLG2016, SLY2016, SCD5584A 2006-01-23 8 Design Considerations For details on design and applications of the SLX2016 in multiple display systems, refer to Appnote 15 at www.osram-os.com Electrical & Mechanical Considerations Voltage Transient Suppression We recommend that the same power supply be used for the dis- play and the components that interface with the display to avoid logic inputs higher than VCC. Additionally, the LEDs may cause transients in the power supply line while they change display states. The common practice is to place 0.01 mF capacitors close to the displays across VCC and GND, one for each display, and one 10 µF capacitor for every second display. ESD Protection The CMOS IC of the SLX2016 is resistant to ESD damage and capable of withstanding discharges less than 2.0 kV. However, take all the standard precautions, normal for CMOS components. These include properly grounding personnel, tools, tables, and transport carriers that come in contact with unshielded parts. If these conditions are not, or cannot be met, keep the leads of the device shorted together or the parts in anti-static packaging. Soldering Considerations The SLX2016 can be hand soldered using a grounded iron set to 260 °C. The display is compatible with leadfree and tin/lead solder. Wave soldering is also possible following these conditions. Preheat does not exceed 93°C on the solder side of the PC board or a package surface temperature of 85°C. Water soluble organic acid flux (ex cept carboxylic acid) or resin-based RMA flux without alcohol can be used. Wave temperature of 245°C +/-5°C with a dwell between 1.5 sec. to 3 sec. Exposure to the wave should not exceed temperatures above 260°C for five seconds at 0.063 inches below the seating plane. The packages should not be immersed in the wave. Post Solder Cleaning Procedures The least offensive cleaning solution is hot D.I. water (60 °C) for less than 15 minutes. Addition of mild saponifiers is acceptable. Do not use commercial dishwasher detergents. For faster cleaning, solvents may be used. Carefully select any sol- vent as some may chemically attack the nylon package. Maximum exposure should not exceed two minutes at elevated tempera tures. Acceptable solvents are TF (trichorotrifluorethane), TA, 111 Trichloroethane, and unheated acetone. Note: Acceptable commercial solvents are: Basic TF , Arklone, P . Genesolv, D. Genesolv DA, Blaco-Tron TF and Blaco-Tron TA. Unacceptable solvents contain alcohol, methanol, methylene chlo- ride, ethanol, TP35, TCM, TMC, TMS+, TE, or TES. Since many com- mercial mixtures exist, contact a solvent vendor for chemical composition information. Some major solvent manufacturers are: Allied Chemical Corporation, Specialty Chemical Division, Morris town, NJ; Baron-Blakeslee, Chicago, IL; Dow Chemical, Midland, MI; E.I. DuPont de Nemours & Co., Wilmington, DE. For further information refer to Appnotes 18 and 19 at www.osram-os.com An alternative to soldering and cleaning the display modules is to use sockets. Standard pin DIP sockets 7.62 mm (0.300") wide with 2.54 mm (0.100") centers work well for single displays. Multiple display assemblies are best handled by longer SIP sockets or DIP sockets when available for uniform package alignment. Socket manufacturers are Aries Electronics, Inc., Frenchtown, NJ; Garry Manufacturing, New Brunswick, NJ; Robinson-Nugent, New Albany, IN; and Samtec Electronic Hardware, New Albany, IN. For further information refer to Appnote 22 at www.osram-os.com Optical Considerations The 4.72 mm (0.180") high characters of the SLX2016 gives readability up to eight feet. Proper filter selection enhances read - ability over this distance. Filters enhance the contrast ratio between a lit LED and the character background intensifying the discrimination of different characters.The only limitation is cost. Take into consideration the ambient lighting envi ronment for the best cost/benefit ratio for filters. Incandescent (with almost no green) or fluorescent (with almost no red) lights do not have the flat spectral response of sunlight. Plas tic band-pass filters are an inexpensive and effective way to strengthen contrast ratios.The SLR2016 is a standard red display and should be matched with long wavelength pass filter in the 600 nm to 620 nm range. The SLO2016 is a super-red display and should be matched with a long wavelength pass filter in the 470 nm to 590 nm range. The SLG/SL Y2016 should be matched with a yellow-green band-pass fil- ter that peaks at 565 nm. For displays of multiple colors, neutral den- sity gray filters offer the best compromise. Additional contrast enhancement is gained by shading the dis- plays. Plastic band-pass filters with built-in louvers offer the next step up in contrast improvement. Plastic filters can be improved further with anti-reflective coatings to reduce glare. The trade-off is fuzzy characters. Mounting the filters close to the display reduces this effect. Take care not to overheat the plastic filter by allowing for proper air flow. Optimal filter enhancements are gained by using circular polar- ized, anti-reflective, band-pass filters. Circular polarizing further enhances contrast by reducing the light that travels through the fil- ter and reflects back off the display to less than 1%. Several filter manufacturers supply quality filter materials. Some of them are: Panelgraphic Corporation, W. Caldwell, NJ; SGL Homa lite, Wilmington, DE; 3M Company, Visual Products Division, St. Paul, MN; Polaroid Corporation, Polarizer Division, Cambridge, MA; Marks Polarized Corporation, Deer Park, NY , Hoya Optics, Inc., Fremont, CA. One last note on mounting filters: recessing displays and bezel assemblies is an inexpensive way to provide a shading effect in overhead lighting situations. Several Bezel manufacturers are: R.M.F . Products, Batavia, IL; Nobex Components, Griffith Plastic Corp., Burlingame, CA; Photo Chemical Products of California, Santa Monica, CA; I.E.E.-Atlas, Van Nuys, CA.
