HI-8590
ARINC 429 LINE DRIVER AND LINE RECEIVER
DESCRIPTION
The HI-8590 is a CMOS integrated circuit with independ-
ent ARINC 429 line driver and line receiver in a single
16 pin package. Both ARINC 429 functions are imple-
mented in analog/digital CMOS.
The line driver function in the HI-8590 connects directly to
the ARINC bus and translates CMOS/TTL input levels to
ARINC 429 specified amplitudes using built-in zeners.
The slope of the differential output signal is controlled by a
single logic input without the use of any external capaci-
tors. A internal 37.5 ohm resistor is provided in series with
each line driver output. The line driver function is the
same as Holt's 8 pin stand-alone HI-8585 line driver.
The line receiver interfaces directly to the ARINC 429 bus
and translates incoming ARINC levels to levels compati-
ble with CMOS logic. Internal comparator levels are set
just below the standard 6.5 volt minimum data threshold
and just above the standard 2.5 volt maximum null thresh-
old
The TESTA and TESTB inputs of the line receiver allow
bypassing the analog input circuitry for testing purposes.
Also, if both test inputs are taken high, the receiver's digital
outputs are tri-stated allowing wire-or possibilities. The
line driver function is the same as Holt's 8 pin stand-alone
HI-8588 line receiver.
