ARINC 429
3.3V Terminal IC
GENERAL DESCRIPTION
APPLICATIONS
The HI-3582/HI-3583 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-3582/HI-3583 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-3582/HI-3583 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 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-3582/HI-3583 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.

FUNCTIONAL DESCRIPTION (cont.)
RECEIVER PARITY
The 32nd bit of received ARINC words stored in the receive FIFO
is used as a Parity Flag indicating whether good Odd parity is
received from the incoming ARINC word.
Odd Parity Received
The parity bit is reset to indicate correct parity was received
and the resulting word is written to the receive FIFO.
Even Parity Received
The receiver sets the 32nd bit to a “1”, indicating a parity error
and the resulting word is then written to the receive FIFO.
Therefore, the 32nd bit retrieved from the receiver FIFO will always
be “0” when valid (odd parity) ARINC 429 words are received.
RETRIEVING DATA
Once 32 valid bits are recognized, the receiver logic generates an
End of Sequence (EOS). Depending upon the state of control
register bits CR2-CR11, the received ARINC 32-bit word is then
checked for correct decoding and label matching before being
loaded into the 32 x 32 receive FIFO. ARINC words which do not
meet the necessary 9th and 10th ARINC bit or label matching are
ignored and are not loaded into the receive FIFO. The following
table describes this operation.
