HI-8596

Single-Rail ARINC 429 Differential Line Driver

The HI-8596 bus interface product is a silicon gate CMOS device designed as a line driver in accordance with the ARINC 429 bus specifications. The part includes a dual polarity voltage doubler, allowing it to operate from a single +3.3V supply using only four external capacitors. The part also features high-impedance outputs (tri-state) when both data inputs are taken high, allowing multiple line drivers to be connected to a common bus.

Logic inputs feature built-in 4KV ESD input protection (HBM) as well as 5V or 3.3V logic level compatibility. 37.5 Ohm or 5 Ohm resistors in series with each ARINC output are available to allow the use of external resistors for lightning protection.

The HI-8596 line driver is intended for use where logic signals must be converted to ARINC 429 levels such as when using an FPGA or the HI-3586 ARINC 429 protocol IC. The part is available in Industrial -40°C to +85°C, or Extended, -55°C to +125°C temperature ranges. Optional burn-in is available on the extended temperature range.
