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 of HI-8444 and HI-8445  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. HI-8444 and HI-8445  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.
