HI-3185, HI-3186, HI-3188

The HI-3182, HI-3183, HI-3184, HI-3185, HI-3186 and HI-3188

bus interface products are silicon gate CMOS devices designed

as a line driver in accordance with the ARINC 429 bus specifica-

tions. In addition to being functional upgrades of Holt's HI-8382

&

HI-8383 products, they are also alternate sources for the

HS-3182 ( Intersil/Harris), the RM3182 (Fairchild /Raytheon)

and a variety of similar line driver products from other manufac-

turers.

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.

Products with 0, 13 or 37.5 ohm resistors in series with each

ARINC output are available.

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-3282/HI-8282A ARINC 429 Serial

Transmitter/Dual Receiver, the HI-6010 ARINC 429 Transmit-

ter/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.
