HI-3584A
ARINC 429 3.3V Serial Transmitter
and Dual Receiver with High-Speed Interface
July 2013
GENERALDESCRIPTION
APPLICATIONS
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 high-
speed host CPU interface compared with the earlier HI-
3584 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.

See Note below
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 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 andTTLcompatible.

The HI-3584A applies the ARINC protocol to the receivers
and transmitter. Timing is based on a 1 Megahertz clock.
(Note: All 3 VDD pins must be connected to the same 3.3V supply)

Chip-Scale Package
Additional interface circuitry such as the Holt HI-8570 or
HI-8571 is required to translate the transmitter’s 3.3 volt
logic outputs to ARINC 429 drive levels.
FEATURES
• ARINC specification 429 compatible
• 3.3V logic supply operation
