HI-3584

Enhanced ARINC 429

3.3V Serial Transmitter and Dual Receiver

GENERAL DESCRIPTION

The HI-3584 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-3584 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-3584âs status

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 to allow users to more easily add

external lightning protection circuitry.

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-3584 applies the ARINC protocol to the receivers

and transmitter. Timing is based on a 1 Megahertz clock.

Additional interface circuitry such as the Holt HI-8585 or

HI-8586 is required to translate the transmitterâs 3.3 volt

logic outputs to ARINC 429 drive levels.
