GENERAL DESCRIPTION
The HI-8584 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-8584 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-8584’s 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 to allow users to more easily add
external lightning protection circuitry. The device can be
used at nonstandard data rates when an option pin, NFD, 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-8584 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,
HI-8586 or HI-3182 is required to translate the transmit-
ter’s 5 volt logic outputs to ARINC 429 drive levels.
