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. 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-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 updated HI-318X and HI-8585 ARINC 429 line drivers are
recommended for all new designs where logic signals must be
converted to ARINC 429 levels such as a user ASIC, the
HI-3282 or HI-8282A ARINC 429 Serial Transmitter/Dual
Receiver, 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,
including data sheets for any of the Holt products
above

... TTL/CMOS compatible. Besides reducing chip current drain, STROBE also floats each output. However the overvoltage fuses and diodes of the HI-8382 are not switched out. Figure 1 illustrates a typical ARINC 429 bus application. Three power supplies are necessary to operate the HI-8382; typically +15V, -15V and +5V. The chip also works with ±12V supplies ...
