HI-8591
ARINC 429 LINE RECEIVER
DESCRIPTION
The HI-8591 is an ARINC 429 bus interface receiver
designed to operate from a single 3.3 V or 5 V supply. The
part is designed with high-impedance inputs to minimize
bus loading, and has an exceptional input common-mode
performance in excess of +/- 30V, making it immune to
ground offsets around the aircraft. The RINA and RINB
inputs of the standard HI-8591 may be connected directly
to the ARINC 429 bus. To enable external lightning protec-
tion circuitry to be added, the HI-8591-40 variant is avail-
able. The HI-8591-40 requires only the addition of external
40 KW, ¼ watt resistors in series with RINA and RINB to
allow the part to meet the lightning protection requirements
of DO-160D level 3.
The typical 10 volt differential ARINC 429 signal is trans-
lated and input to a window comparator and latch. The
comparator levels are set just below the standard 6.5 volt
minimum ARINC data threshold and just above the stan-
dard 2.5 volt maximum ARINC null threshold.
The TESTA and TESTB inputs bypass the analog inputs for
testingwww.DataSheet4U.com purposes. Also if TESTA and TESTB are both taken
high, the digital outputs are forced to zero.
See Holt Application Note AN-300 for more information on
lightning protection.
FEATURES
! ARINC 429 line receiver interface in a
small outline package
! 3.3V single rail supply voltage
! +/-30 V common-mode performance
! >140 KOhm input impedance
! Lightning protection simplified with the
ability to add 40 KOhm external series
resistors
! Receiver input hysteresis at least 2 volt
! Test inputs bypass analog inputs and
force digital outputs to a one, zero or
null state
