HI-8588
January 2001
DESCRIPTION
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.
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.
The TESTA and TESTB inputs bypass the analog for
testing purposes. Also if TESTA and TESTB are both
taken high, the analog powers down and the digital outputs
tri-state allowing wire-or possibilities.
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
TESTA and TESTB are both high.
