HI-8456

December 2016 HI-8456, HI-8457, HI-8458 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 VOC/ISC 300V/60A Waveform 5A VOC/ISC 300V/300A Waveform 5B VOC/ISC 300V/300A The devices are designed to operate from either a 5V or 3.3V supply in a high noise environment, with an input common mode voltage range of ±30V. Each receiver channel translates incoming ARINC 429 data bus signals to a pair of TTL / CMOS outputs. FEATURES Internal lightning protection circuitry ensure...
