www.DataSheet4U.com HI-8444, HI-8445, HI-8448 Quad / Octal ARINC 429 Line Receivers January 2003 DESCRIPTION The HI-8444 and HI-8445 are quad ARINC 429 line receiver ICs available in a 20-pin TSSOP package. The HI8448 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 10 Kohm series resistor. The “-10” devices meet the lightning protection requirements of DO-160C/D level 3, waveforms 3, 4, and 5A. The TESTA and TESTB inputs bypass the analog inputs for testing purposes.
