GENERAL DESCRIPTION
The HI-8584 from Holt Integrated Circuits is a silicon gate CMOS device for interfacing a 16-bit parallel data bus to the ARINC 429 serial bus. The HI-8584 design offers many enhancements to the industry standard HI-8282 architecture. The device provides two receivers each with label recognition, a 32 by 32 FIFO, and an analog line receiver. Up to 16 labels may be programmed for each receiver. The independent transmitter also has a 32 by 32 FIFO. The status of all three FIFOs can be monitored using the external status pins or by polling the HI-8584’s status register.
