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/CMOSoutputs. The optional HI-8444-10, HI-8445-10 and HI-8448-10 are designed to be used with an external 10 Kohm series resistor. The "-10" devices meet the lightning protection requirements of DO-160C/D level 3, waveforms 3, 4, and 5A.

The TESTAand 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 andTESTB pins are not available.
