DEI1170A, DEI1171A ARINC 429 LINE DRIVER WITH RATE SELECT and TRI-STATE

2022-09-20
●GENERAL DESCRIPTION
■The DEI1170A/DEI1171A bipolar 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. 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. A429 output tristate capability is enabled by the TS_CTL input.
●FEATURES
■TTL/CMOS to ARINC 429 Line Driver
■HI/LO Speed Control Pin for Hi (100KBS) or Lo (12.5KBS) speed slew rates
■±9.5V to ±16.5V supplies
■Drives full ARINC load
■Output resistor options: 0, 10 or 37.5 Ohms
■Tristate Output feature
■Thermally enhanced 5 x 5 mm MLP package
■The DEI1170A family is an improved version of the popular DEI1170 family
