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. 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.

ARINC 429 Receiver Timing
INTERNAL LIGHTNING PROTECTION (-10 Only)
The HI-8444-10, HI-8445-10 and HI-8488-10 are similar to the “non -10” configurations with the exception that an external 10 Kohm resistor must be added in series with each ARINC input in order to properly detect the ARINC 429 specified input thresholds. This option is especially useful in applications where external lightning protection circuitry is required.
Test Mode Timing
The HI-8444-10, HI-8445-10 and HI-8448-10 will meet the requirements of DO-160D, Level 3, waveforms 3, 4 and 5A with the 10 Kohm series resistors in place. Please refer to the Holt AN-300 Application Note for additional information and recommendations on lightening protection of Holt Line Drivers and Receivers.
