GENERAL DESCRIPTION

The HI-8482 bus interface unit is a silicon gate CMOS device designed as a dual differential line receiver in accordance with the requirements of theARINC 429 bus specification. The device translates incoming ARINC 429 signals to normal CMOS/TTL levels on each of its two independent 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, theARINC inputs are ignored.

FEATURES

• Converts ARINC 429 levels to digital data

• Direct replacement for the RM3183

• Greater than 2 volt receiving hysteresis

• TTL and CMOS outputs and test inputs

• Military screening available

• 20-Pin SOIC, PLCC, CERQUAD, DIP & LCC packages are available
