HI-8588
ARINC 429 LINE RECEIVER
August 2006
DESCRIPTION
PIN CONFIGURATION
The HI-8588 is an ARINC 429 bus interface receiver and is
available in a SO 8 pin package. The technology is
analog/digital CMOS. The circuitry requires only a 5 volt
supply.
VCC - 1
TESTA - 2
RINB - 3
RINA - 4
8 - TESTB
7 - ROUTB
6 - ROUTA
5 - GND
8588PS
The ARINC bus can be connected directly to the chip. The
typical 10 volt differential signal is translated and input to a
window comparator and latch. The comparator levels are
just below the standard 6.5 volt minimum ARINC data
threshold and just above the standard 2.5 volt maximum
ARINC null threshold.
8 - PIN PLASTIC NARROW BODY SOIC
SUPPLY VOLTAGES
The TESTA and TESTB inputs bypass the analog for
testing purposes. Also if TESTAand TESTB are both taken
high, the analog powers down and the digital outputs tri-
state allowing wire-or possibilities.
vcc = 5.0V 5%
Please refer to the HI-8588-10 for applications where an
external resistance in series with the ARINC inputs is
required for lightning protection or when the digital outputs
need to be a logic zero rather than open circuit when
TESTAandTESTB are both high.
