HI-8444, HI-8445, HI-8448

May 2010

Quad / Octal

ARINC 429 Line Receivers

PIN CONFIGURATIONS

(See page 6 for additional pin configurations)

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.
