GENERAL DESCRIPTION
The HI-3182, HI-3183, HI-3184, HI-3185, HI-3186, HI-3187 and
HI-3188 bus interface products are silicon gate CMOS devices
designed as a line driver in accordance with the ARINC 429 bus
specifications. 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 HI-3182, HI-3184
and HI-3187 products also have a 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.
