PIN CONFIGURATIONS
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 β€œ-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.

INTERNAL LIGHTNING PROTECTION (-10 Only)
The HI-8444-10, HI-8445-10 and HI-8488-10 are similar to the
β€œnon -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.
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.
