DESCRIPTION
The HI-8444 and HI-8445 are quad ARINC 429 line
receiver ICs available in a 20-pin TSSOP package. The HI-
8448 contains 8 independent ARINC 429 line receivers.
The technology is analog / digital CMOS. The device is
designed to operate from either a 5V or 3.3V supply. Each
receiver channel translates incoming ARINC 429 data bus
signals to a pair of TTL / CMOS outputs.
The optional HI-8444-10, HI-8445-10 and HI-8448-10 are
designed to be used with an external 15 Kohm series
resistor. The “-10” devices meet the lightning protection
requirements of DO-160E, level 3, waveforms 3, 4, 5A, and
5B.
The TESTA and TESTB inputs bypass the analog inputs for
testing purposes. They force the receiver outputs to the
specified ZERO, ONE or NULL state. The ARINC inputs
are ignored when the device is in the test mode.
The HI-8445 is identical to the HI-8444 except the TESTA
and TESTB pins are not available.
