HI-8597
3.3V Single-Rail ARINC 429 Differential Line Driver with Integrated DO-160G Level 3 Lightning Protection
GENERAL DESCRIPTION
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/DO160G, 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. Pin surge levels for Level 3 are summarized as follows:
Waveform 3
Voc/Isc
600V/24A
Waveform 4
Voc/Isc
300V/60A
Waveform 5A
Voc/Isc
300V/300A
Waveform 5B
Voc/Isc
300V/300A
An internal 37.5 Ohm resistor on each output enables direct connection to the ARINC 429 bus.
