The HI-8597 is a 3.3V single supply ARINC 429 line driver with built-in lightning protection. The internal lightning protection circuitry allows compliance with RTCA/DO-160G, Section 22 Level 3 Pin Injection Test Waveform Set A (3 & 4), Set B (3 & 5A) and Set Z (3 & 5B) without the use of any external components, an industry first. An internal 37.5 Ohm resistor on each output enables direct connection to the ARINC 429 bus. In addition, the device includes a dual polarity voltage doubler, allowing it to operate from a single +3.3V supply using only four external capacitors.
