The comparator levels are set just below the standard 6.5 volt minimum ARINC data threshold and just above the standard 2.5 volt maximum ARINC null threshold.

The part is designed with high-impedance inputs to minimize bus loading, and has an exceptional input common-mode performance in excess of +/- 30V, making it immune to ground offsets around the aircraft. The RINA and RINB inputs of the standard HI-8591 may be connected directly to the ARINC 429 bus. To enable external lightning protection circuitry to be added, the HI-8591-40 variant is available. The HI-8591-40 requires only the addition of external 40 KW, ¼ watt resistors in series with RINA and RINB to allow the part to meet the lightning protection requirements of DO-160D level 3.

Figure 1 shows the general architecture of the ARINC 429 receiver. The receiver operates off the VCC supply only. The inputs RINA and RINB each require 140KW of resistance between the ARINC bus and comparator. This resistance is completely on-chip for the HI-8591. In contrast, the HI-8591-40 has 100 KW on-chip and requires an external 40KW, ¼ watt resistor on each of the ARINC 429 input pins. The HI-8591-40 device is typically chosen for applications where lightning protection is a requirement. The status of the ARINC receiver input is latched. A Null input resets the latches and a One or Zero input sets the latches. The logic at the output is controlled by the test signal which is generated by the logical OR of the TESTA and TESTB pins. If TESTA and TESTB are both One, the HI8591 outputs are pulled low. This allows the digital outputs of a transmitter to be connected to the test inputs through control logic for system self-test purposes. After level translation, the inputs are buffered and become inputs to a differential amplifier. The amplitude of the differential signal is compared to levels derived from a divider between V.C. and Ground.
