GENERAL DESCRIPTION
PIN CONFIGURATIONS (Top Views)
The HI-8482 bus interface unit is a silicon gate CMOS de-
vice designed as a dual differential line receiver in accor-
dance with the requirements of the ARINC 429 bus spec-
ification. The device translates incoming ARINC 429 sig-
nals to normal CMOS/TTL levels on each of its two inde-
pendent receive channels. The HI-8482 is also function-
ally equivalent to the Fairchild/Raytheon RM3183.
The self-test inputs force the outputs to either a ZERO,
ONE, or NULL state for system tests. While in self-test
mode, the ARINC inputs are ignored.
All the ARINC inputs have built-in hysteresis to reject
noise that may be present on the ARINC bus. Additional
input noise filtering can also be accomplished with exter-
nal capacitors.

The HI-8482 line receiver is one of several options of-
fered by Holt Integrated Circuits to interface to the ADRaINtaCSheet4U.com
bus. The digital data processing for serial-to-parallel con-
version and clock recovery can be accomplished with the

D1695

This part is a darlington connection NPN silicon epitaxial transistor. The 2SD1695 is a Darlington connection transistor and incorporates a dumper diode between the collector and emitter and a constant voltage diode and protection elements between the collector and base. This transistor is ideal for drives in solenoid and actuators.
