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/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. Each device
contains 8 independent ARINC 429 line receivers. Pin
surge levels for Level 3 are summarized below.

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 ensures
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)
Direct connection to ARINC 429 bus with no
external components
High input common mode voltage range of ±30V
Non-annunciated fault protection; a receiver will
reject a signal when either bus line is open or
shorted to ground.
3.3V or 5.0V single supply operation
Test inputs bypass analog inputs and force digital
outputs to a one, zero, or null state (not available
on HI-8457)
Industrial and Extended temperature ranges
Burn-in available
In the case of HI-8456 and HI-8458, the TESTA and
TESTB inputs bypass the analog inputs for testing
purposes. They force the outputs of all eight receivers
to the specified ZERO, ONE or NULL state. The ARINC
inputs are ignored when the devices are in test mode.
The HI-8456 has a single test port which controls
all 8 channels simultaneously. The HI-8458 has two
independent test ports, each controlling a bank of 4
channels. Test inputs are not implemented on HI-8457
and are internally connected to logic 0. The truth table
for the TESTA and TESTB inputs is shown in Table 1.
The HI-8456 and HI-8457 are exact drop in replacements
for DEI1046 and DEI1047 respectively. The HI-8458 is
pin-to-pin compatible with Holt’s HI-8448 and is also a
drop-in replacement for the DEI1148 (44-pin PQFP). A
part number cross reference is included in Table 2.
The parts are available in Industrial -40oC to +85oC, or
Extended, -55oC to +125oC temperature ranges. Optional
burn-in is available on the extended temperature range.
