DESCRIPTION
The HI-8588-10 ARINC 429 bus interface receiver is simi-
lar to the HI-8588 with the exception that it allows an exter-
nal 10 Kohm resistor in series with each ARINC input with-
out affecting the ARINC input thresholds. The product is
especially useful in applications where lightning protection
circuitry is also required. In addition, the test inputs force
both of the outputs to zero instead of open circuit. The ana-
log/digital CMOS product requires only a 5 volt supply and
is available in a 8-pin SOIC package.
Each side of the ARINC bus must be connected through a
10 Kohm series resistor in order for the chip to detect the
correct ARINC levels. The typical 10 volt differential signal
is translated and input to a window comparator and latch.
The comparator levels are set so that with the external
10 Kohm resistors they are 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
testing 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.
