Description
The IL715, IL716 and IL717 series of 4–channel digital isolators provide the designer with the most compact isolated logic devices yet available. These isolators are packaged in three options: IL715 with four unidirectional channels, IL716 with two channels in one direction and two channels in the opposite direction, and the IL717 with three channels in one direction and one channel in the other direction. All these devices are fabricated with patented* IsoLoop® technology giving them excellent transient immunity specifications. The symmetric magnetic coupling barrier gives these isolators a propagation delay of only 10 ns and a pulse width distortion of 2 ns. Devices are 100% high voltage tested to guarantee barrier integrity. The IL715, IL716 and IL717 have a 100 MBaud data rate which is independent of direction. They are available in 0.3” and 0.15” 16–pin SOIC packages and are specified over the temperature range –40ºC to +100ºC.

It does not guarantee performance. PWD is defined as | tPHL– tPLH |. %PWD is equal to the PWD divided by the pulse width. tPSK is equal to the magnitude of the worst case difference in tPHL and/or tPLH that will be seen between units at 25 OC. CMH is the maximum common mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD. CML is the maximum common mode input voltage that can be sustained while maintaining VO < 0.8 V. The common mode voltage slew rates apply to both rising and falling common mode voltage edges. Device is considered a two terminal device: pins 1–8 shorted and pins 9–16 shorted. 250 200 100 0 0 TEMPERATURE (ºC ) ROOM TEMPERATURE 100 150 200 250 TIME (SECONDS) 160ºC 150ºC 140ºC PRE HEATING TIME 2.5ºC ±0.5ºC / SEC PEAK TEMPERATURE 245º C PEAK TEMPERATURE 240° C PEAK TEMPERATURE 230ºC SOLDERING TIME 200ºC PRE HEATING RATE 3ºC + 1ºC /-0.5ºC /SEC.

By detecting the edge transitions of the input logic signal and converting these to narrow current pulses a magnetic field is created around the GMR Wheatstone bridge. Depending on the direction of the magnetic field, the bridge causes the output comparator to switch following the input logic signal. Since the current pulses are narrow, about 2.5ns wide, the power consumption is independent of mark-to-space ratio and solely dependent on frequency. This has obvious advantages over optocouplers whose power consumption is heavily dependent on its on-state and frequency. The approximate power supply current per channel for Isoloop® is: I(input)= 40 . f 1 mA fmax where operating frequency fmax=
50 MHz
Both power supplies to these devices should be decoupled with good quality 47 nF ceramic capacitors. For data rates in excess of 10MBd, use of ground planes for both GND1 and GND2 is highly recommended. Capacitors should be located as close as possible to the device. Signal Status on Start-up and Shut Down To minimize power dissipation, the input signals to the IL715, IL716 and IL717 are differentiated and then latched on the output side of the isolation barrier to reconstruct the signal. This could result in an ambiguous output state depending on power up, shutdown and power loss sequencing. Therefore, the designer should consider the inclusion of an initialization signal in his start-up circuit. Data Transmission Rates The reliability of a transmission system is directly related to the accuracy and quality of the transmitted digital information. For a digital system, those parameters which determine the limits of the data transmission are pulse width distortion and propagation delay skew. Propagation delay is the time taken for the signal to travel through the device. This is usually different when sending a low-to-high than when sending a high-to-low signal. This difference, or error, is called pulse width distortion (PWD) and is usually in ns. It may also be expressed as a percentage: This figure is almost 3x better than for any available optocoupler with the same temperature range, and 2x better than any optocoupler regardless of published temperature range. The IsoLoop® range of isolators including the IL717 surpasses the 10% maximum PWD recommended by PROFIBUS, and will run at almost 35 Mb before reaching the 10% limit. Propagation delay skew is the difference in time taken for two or more channels to propagate their signals. This becomes significant when clocking is involved since it is undesirable for the clock pulse to arrive before the data has settled. A short propagation delay skew is therefore critical, especially in high data rate parallel systems, to establish and maintain accuracy and repeatability. The IsoLoop® range of isolators all have a maximum propagation delay skew of 6 ns, which is 5x better than any optocoupler. The maximum channel to channel skew in the IL717, IL716, and IL715 isolators is only 3 ns which is 10x better than any optocoupler. Application Notes: PWD% = Maximum Pulse Width Distortion (ns) x 100% Signal Pulse Width (ns) e.g. for the IL717 @ 12.5 Mb PWD% = 3 ns x 100% = 3.75% 80 ns
