HI-8456, HI-8457, HI-8458Octal ARINC 429 Line Receivers withIntegrated DO-160G Level 3 Lightning ProtectionApril 2020GENERAL DESCRIPTIONFEATURESHolt’s family of octal ARINC 429 line receivers, HI-8456,HI-8457 and HI-8458 include internal lightning protectioncircuitry which ensures compliance with RTCA/DO160G, Section 22 Level 3 Pin Injection Test WaveformSet A (3 & 4), Set B (3 & 5A) and Set Z (3 & 5B) withoutthe use of any external components. Each devicecontains 8 independent ARINC 429 line receivers. Pinsurge levels for Level 3 are summarized V/300AThe devices are designed to operate from either a 5V or3.3V supply in a high noise environment, with an inputcommon mode voltage range of 30V. Each receiverchannel translates incoming ARINC 429 data bussignals to a pair of TTL / CMOS outputs.In the case of HI-8456 and HI-8458, the TESTA andTESTB inputs bypass the analog inputs for testingpurposes. They force the outputs of all eight receiversto the specified ZERO, ONE or NULL state. The ARINCinputs are ignored when the devices are in test mode.The HI-8456 has a single test port which controlsall 8 channels simultaneously. The HI-8458 has twoindependent test ports, each controlling a bank of 4channels. Test inputs are not implemented on HI-8457and are internally connected to logic 0. The truth tablefor the TESTA and TESTB inputs is shown in Table 1.The HI-8456 and HI-8457 are exact drop in replacementsfor DEI1046 and DEI1047 respectively. The HI-8458 ispin-to-pin compatible with Holt’s HI-8448 and is also adrop-in replacement for the DEI1148 (44-pin PQFP). Apart number cross reference is included in Table 2.ooThe parts are available in Industrial -40 C to 85 C, orooExtended, -55 C to 125 C temperature ranges. Optionalburn-in is available on the extended temperature range.

The receiver operates off the VDD supply only. Theinputs INA and INB may be connected directly to the ARINC 429 bus. Internal lightning protection circuitry ensurescompliance with RTCA/DO-160G, Section 22 Level 3 Pin Injection Test Waveform Set A (3 & 4), Set B (3 & 5A) andSet Z (3 & 5B) without the use of any external components.After level translation, the inputs are buffered and become inputs to a differential amplifier. The amplitude of thedifferential signal is compared to levels derived from a divider between VDD and Ground. The nominal settingscorrespond to a One/Zero amplitude of 6.0V and a Null amplitude of 3.3V.The status of the ARINC receiver input is latched. A Null input resets the latches and a One or Zero input sets thelatches.The logic at the output is controlled by the test signal which is generated by the logical OR of the TESTA and TESTBpins (not available on HI-8457). If TESTA and TESTB are both One, the outputs are pulled low. This allows the digitaloutputs of a transmitter to be connected to the test inputs through control logic for system self-test purposes.HOLT INTEGRATED CIRCUITS2Downloaded from Arrow.com.
