Octal ARINC 429 Line Receivers with Integrated DO-160G Level 3 Lightning Protection
GENERAL DESCRIPTION
Holt’s family of octal ARINC 429 line receivers, HI-8456, HI-8457 and HI-8458 include internal lightning protection circuitry which ensures 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. Each device contains 8 independent ARINC 429 line receivers. Pin surge levels for Level 3 are summarized below.
Waveform 3
VOC/ISC
600V/24A
Waveform 4
