com DEI1073, DEI1074, DEI1075 ARINC 429 LINE DRIVER WITH RATE SELECT AND TRI-STATE FEATURES • TTL/CMOS TO ARINC 429 Line Driver.
• Rate control input set Hi (100KBS) or Lo (12.
5KBS) speed slew rates.
• Operates from ±9.
5V to ±16.
5V power supply.
• Drives full ARINC load.
• Output resistor options: 0, 10 or 37.
5 Ohms.
• Tristate Outputs • Thermally enhanced 8 lead SOIC package.
• Outputs Short Circuit Tolerant GENERAL DESCRIPTION The DEI1073 family of 8 pin BiCMOS integrated circuits are line drivers designed to directly drive the ARINC 429 avionics serial digital data bus.
The device converts TTL/CMOS serial input data to the tri-level RZ bipolar differential modulation format of the ARINC bus.
The outputs are tri-state capable.
A TTL/CMOS control input selects the output slew rate for HI (100KBS) and LOW (12.
5KBS) speed operation.
No external timing capacitors are required.
The DEI1073 has internal 37.
5 Ohm output resistors, the DEI1074 has 10 Ohm resistors, and the DEI1075 has none.
The 10 and 0 Ohm options require external series resistors which are typically used to implement a transient voltage protection network.
