HI-3583A

July 2013 HI-3582A, HI-3583A ARINC 429 3.3V Terminal IC with High-Speed Interface GENERAL DESCRIPTION The HI-3582A/HI-3583A from Holt Integrated Circuits are silicon gate CMOS devices for interfacing a 16-bit parallel data bus directly to the ARINC 429 serial bus. The HI-3582A/HI-3583A design offers a high-speed host CPU interface compared with the earlier HI-3582/HI-3583 products. 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-3582A/HI-3583A 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 and output resistance to allow users to more easily...
