Single-Rail ARINC 429 Differential Line Driver
GENERAL DESCRIPTION
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 in-
cludes a negative voltage converter allowing it to oper-
ate from a single +5V supply using only two external ca-
pacitors. 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 ver-
sions 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 -40^oC to
+85^oC, or Extended, -55^oC to +125^oC temperature rang-
es. Optional burn-in is available on the extended tem-
perature range.
