Line Receiver

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 SOICpackage. By Holt Integrated Circuits, Inc.
