The HI-3182, HI-3184 and HI-3185 bus interface products are

silicon gate CMOS devices designed as a line driver in accor-

dance with the ARINC 429 bus specifications. In addition to

being functional upgrades of Holt's HI-8382 product, they are

also alternate sources for a variety of similar line driver products

from other manufacturers.

Inputs are provided for clocking and synchronization. These

signals are AND'd with the DATA inputs to enhance system

performance and allow the HI-318X series of products to be

used in a variety of applications. Both logic and synchronization

inputs feature built-in 2,000V minimum ESD input protection as

well as TTL and CMOS compatibility.

The differential outputs of the HI-318X series of products are

programmable to either the high speed or low speed ARINC 429

output rise and fall time specifications through the use of two

external capacitors. The output voltage swing is also adjustable

by the application of an external voltage to the VREF input. A

37.5 ohm

resistor is in series with each ARINC output.

In

addition the

fuse in

series with each output.

The HI-318X series of line drivers are intended for use where

logic signals must be converted to ARINC 429 levels such as

when using an ASIC, the HI-8584/HI-3282/HI-8282A

ARINC 429 Serial Transmitter/Dual Receivers, the HI-6010

ARINC 429 Transmitter/Receiver or the HI-8783 ARINC

Interface Device.

Holt products are readily available for both

industrial and military applications. Please contact the Holt

Sales Department for additional information.
