The HI-3182, and HI-3185 bus interface products are silicon
gateCMOSdevicesdesignedasalinedriverinaccordancewith
the ARINC 429 bus specifications. In addition to being func-
tionalupgradesofHolt'sHI-8382product,theyarealsoalternate
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
usedinavarietyofapplications. Bothlogicandsynchronization
inputs feature built-in 2,000V minimum ESD input protection as

The differential outputs of the HI-318X series of products are
programmable to either the high speed or low speedARINC 429
output rise and fall time specifications through the use of two
externalcapacitors. Theoutputvoltageswingisalsoadjustable
by the application of an external voltage to the VREF input. A
37.5 ohm
resistor is in series with each ARINC 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 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.
