GENERAL DESCRIPTION

The HI-8582/HI-8583 from Holt Integrated Circuits are a silicon gate CMOS devices for interfacing a 16-bit parallel data bus directly to the ARINC 429 serial bus. The HI-8582/HI-8583 design offers many enhancements to the industry standard HI-8282 architecture. The device provides two receivers each with label recognition, 32 by 32 FIFO, and analog line receiver. Up to 16 labels may be programmed for each receiver. The independent transmitter has a 32 X 32 FIFO and a built-in line driver. The status of all three FIFOs can be monitored using the external status pins, or by polling the HI-8582/HI-8583 status register.
