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.
ARINC 429 Line Driver for HI speed (100 kHz) and LOW speed (12.5 kHz) data rates
Pin for Pin replacement part for industry standard ARINC 429 Line Drivers
Low EMI RS-422 line driver mode for data rates up to 100 kHz
Adjustable slew rates via two external capacitors
Inputs are TTL and CMOS compatible
Low quiescent power of 125mW (typical)
Programmable output differential range via VREF pin
Outputs are fused for failsafe overvoltage protection
Drives full ARINC load of 400W and 30,000pF
Extended (-55°/+85°) and Military (-55°/+125°) temperature ranges
100% Final Testing
