HI-3584A

July 2013 HI-3584A ARINC 429 3.3V Serial Transmitter and Dual Receiver with High-Speed Interface GENERAL DESCRIPTION The HI-3584A 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-3584A design offers a highspeed host CPU interface compared with the earlier HI3584 product. 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-3584A’s status register. Other features include a programmable option of data or parity in the 32nd bit, and the ability to unscramble the 32 bit word. Also, versions are available with different values of input resistance to allow users to more easily add external lightning protection circuitry. The 16-bit parallel d...
