GENERAL DESCRIPTION
The HI-8282A is a silicon gate CMOS device for interfacing the ARINC 429 serial data bus to a 16-bit parallel data bus. Two receivers and an independent transmitter are provided. The receiver input circuitry and logic are designed to meet the ARINC 429 specifications for loading, level detection, timing, and protocol. The transmitter section provides the ARINC 429 communication protocol. Additional interface circuitry such as the Holt HI-8585, HI-8586 or HI-3182 is required to translate the 5 volt logic outputs toARINC 429 drive levels.
The 16-bit parallel data bus exchanges the 32-bit ARINC data word in two steps when either loading the transmitter or interrogating the receivers. The data bus interfaces with CMOS and TTL.
Timing of all the circuitry begins with the master clock input, CLK. For ARINC 429 applications, the master clock frequency is 1 MHz.

FEATURES
• ARINC specification 429 compliant
• 16-Bit parallel data bus
• Direct receiver interface to ARINC bus
• Timing control 10 times the data rate
• Selectable data clocks
• 8 word transmit FIFO
• Self test mode
• Parity functions
• Low power, single 5 volt supply
• Industrial & extended temperature ranges
• Alternate source to Intersil HS-3282 in all ARINC 429 applications
• Small footprint 44-pin QFP package option
• Automatic transmitter data timing Receiver error rejection per ARINC specification 429
