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
