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 transmit-

ter 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. Other new 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 add external

lightning protection circuitry. The device can be used at

nonstandard data rates when an option pin,

, is

invoked.

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 databus and all control

signals are CMOS and TTL compatible.

The HI-8582/HI-8583 apply the ARINC protocol to the

receivers and transmitter. Timing is based on a 1 Mega-

hertz clock.

Although the line driver shares a common substrate with

the receivers, the design of the physical isolation does not

allow parasitic crosstalk, and thereby achieves the same

isolation as common hybrid layouts.
