HI-8444PST
HI-8444 Series ARINC 429 Line Receiver
The HI-8444/HI-8445 are a quad ARINC 429 Line receiver ICs available in a small footprint 20-pin plastic TSSOP package. Each independent receiver channel translates incoming ARINC 429 data bus signals to an associated pair of CMOS/TTL outputs. Using low-power analog/digital CMOS technology, the line receivers will operate from either a 3.3V or 5V supply. Each ARINC input is internally protected to meet the lightning protection requirements of DO-160C/D Level 3, waveforms 3, 4 & 5A. The HI-8444 has inputs (TESTA & TESTB) that bypass the analog circuitry for testing purposes. They force the receiver outputs to the specified ZERO, ONE or state. The ARINC inputs are ignored when the device is in the test mode. The HI-8444 and HI-8445 are drop-in replacements for DEI1044 and DEI1045.
