PIN DESCRIPTION TABLE

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.

See Holt Application Note AN-300 for more information on

lightning protection.
