GENERAL DESCRIPTION
The HI-8382 and HI-8383 bus interface products are silicon
gate CMOS devices designed as a line driver in accordance with
the ARINC 429 bus specifications.
Inputs are provided for clocking and synchronization. These
signals are AND'd with the DATA inputs to enhance system
performance and allow the HI-8382 to be used in a variety of
applications.
built-in 2,000V minimum ESD input protection as well as TTL
and CMOS compatibility.
The differential outputs of the HI-8382 are independently
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. The
HI-8382 has on-chip Zener diodes in series with a fuse to each
differential output protecting the ARINC bus from an overvoltage
failure. The outputs each have a series resistance of 37.5 ohms.
The HI-8383 is identical to the HI-8382 except that the series
resistors are 13 ohms and the overvoltage protection circuitry
has been eliminated.
The HI-8382 and HI-8383 are intended for use where logic
signals must be converted to ARINC 429 levels such as a user
ASIC or the HI-8282 ARINC 429 Serial Transmitter/Dual
Receiver or the HI-6010 ARINC 429 Transmitter/Receiver. Holt
products are readily available for both industrial and military
applications. Please contact the Holt Sales Department for
additional information, including data sheets for the HI-8282 and
HI-6010 products.
