... 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. FEATURES ! ...
