© 2016 Device Engineering Incorporated 2 of 13 DS-MW-00429-01 Rev. G 01/13/2016 General Description: The BD429 ARINC Line Driver Circuit is a bipolar monolithic IC designed to meet the requirements of several general aviation serial data bus standards. These include the differential bipolar RZ types such as ARINC 429, ARINC 571, and ARINC 575, as well as the differential NRZ types such as the RS-422 standard. Functional Description: Modes: The BD429 operates in either a 429 mode or a 422 mode as controlled by the 429/422´ pin. 429 Mode: In 429 mode, the serial data is presented on the DATA(A) and DATA(B) inputs in the dual rail format defined in the MARK 33 Digital Information Transfer System – ARINC Specification 429-10 . The driver is enabled by the SYNC and CLOCK inputs. The output voltage level is programmed by the V REF input and is normally tied to +5VDC along with V 1 to produce output levels of +5 volts, 0 volts, and –5 volts on each output for ±10 volts differential outputs. * See Figure 4. 422 Mode: In 422 mode, the serial data is presented on DATA(A) input. The driver is enabled by the SYNC and CLOCK inputs. The outputs swings between 0 volts and +5 volts if VREF is at +5VDC. *See Figure 5. Output Resistance: The driver output resistance is 75 W ±20% at room temperature; 37.5 W on each output. The outputs are also fused for failsafe protection against shorts to aircraft power. The output slew rate is controlled by external timing capacitors on CA and CB. Typical values are 75pF for 100 KHz data and 500pF for 12.5 KHz data. Table 1: Truth Table

The voltage on VREF sets the output voltage levels on AOUT and BOUT. The output logic levels swing between +VREF, 0 volts, and –V REF volts. NC No Connect SYNC Logic input. Logic 0 forces outputs to NULL state. Logic 1 enables data transmission. DATA(A) DATA(B) Logic inputs. These signals contain the Serial Data to be transmitted on the ARINC 429 data bus. Refer to Figure 4and Figure 5. CA CB Analog Nodes. External timing capacitors are tied from these points to ground to establish the output signal slew rate. Typical CA = CB = 75pF for 100 kHz data and CA = CB = 500pF for 12.5 kHz data. * AOUT BOUT Outputs. These are the line driver outputs which are connected to the aircraft serial data bus. -V Negative Supply Input. –15VDC nominal. GND Ground. +V Positive Supply Input. +15VDC nominal. CLOCK Logic input. Logic 0 forces outputs to NULL state. Logic 1 enables data transmission. 429/422' Logic Input. Mode control for ARINC 429 and RS-422 modes. An internal 10KW pull up resistor keeps the chip in ARINC 429 mode when there is no external connection. This creates a default logic 1, enabling the ARINC 429 mode. A forced logic 0 enables the RS-422 mode. V1 Logic Supply Input. +5VDC nominal. *CA and CB pin voltages swing between ±5 volts. Any electronic switching of the capacitor on the pins must not inhibit the full voltage swings.

Proper thermal management is important in designs operating at the HI speed data rate (100KBS) with high capacitive loads and high data duty cycles. Power dissipation may be estimated from Table 5 “Power Dissipation Table”. Device power dissipation (Pd) is indicated for 100% data duty cycle with no word gap null times and should be adjusted for the appropriate data duty cycle (DC). Pd(application) = DC * [Pd(table) - 145mW] + 145mW, where DC is the application data duty cycle, Pd(table) is the Pd from the table for the indicated data rate and bus load, and 145mW is the quiescent power. The application’s data duty cycle (DC) for 100KBS operation is calculated as: DC = (total bits transmitted in 10 sec period / 1,000,000) = (32 x total ARINC words transmitted in 10 sec period / 1,000,000). Heat transfer from the IC package should be maximized. Use maximum trace width on all power and signal connections at the IC. Place vias on the signal/power traces close to the IC to maximize heat flow to the internal power planes. If possible, design a solid heat spreader land under and beyond the IC to maximize heat flow from the device.
