HI-8592

Single-Rail ARINC 429 Differential Line Driver

The HI-8592 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 negative voltage converter allowing it to operate from a single +5V supply using only two 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.

The HI-8593 and HI-8594 are reduced pin count versions of HI-8592 which do not incorporate the negative voltage converter. These devices are compatible with Holt’s existing HI-8570 and HI-8571 respectively, with the added advantage of the tri state outputs. For even smaller board footprint, versions are also available in leadless, surface-mount QFN-style packages. Logic inputs feature built-in 2,000V minimum ESD input protection as well as 5V or 3.3V logic level compatibility. Products with 5 Ohm or 37.5 Ohm resistors in series with each ARINC output are available to allow the use of external resistors for lightning protection.

The HI-859x series of line drivers are intended for use where logic signals must be converted to ARINC 429 levels such as when using an FPGA or the HI-3584 ARINC 429 Serial Transmitter/Dual Receiver. The family of parts are available in Industrial -40o C to +85o C, or Extended, -55o C to +125o C temperature ranges. Optional burn-in is available on the extended temperature range.
