The HI-8591 is a single ARINC 429 line receiver available in both 8-pin SOIC and 12-pin LPCC (chip-scale) packages. The product, designed with analog/digital CMOS technology, requires only a single 3.3V or 5V supply. In addition, the test inputs force both of the outputs to zero.

The HI-8591-40 allows an external 40 Kohm resistor to be placed in series with each ARINC input without affecting the ARINC input thresholds. The product is especially useful in applications where lightning protection is also required.
