DESCRIPTION
The HI-8591 is an ARINC 429 bus interface receiver designed to operate from a single 3.3 V or 5 V supply. The part is designed with high-impedance inputs to minimize bus loading, and has an exceptional input common-mode performance in excess of +/- 30V, making it immune to ground offsets around the aircraft. The RINA and RINB inputs of the standard HI-8591 may be connected directly to the ARINC 429 bus. To enable external lightning protection circuitry to be added, the HI-8591-40 variant is available.
