HI-8588-10 ARINC 429 LINE RECEIVER July 2006 DESCRIPTION PIN CONFIGURATION The HI-8588-10 ARINC 429 bus interface receiver is similar to the HI-8588 with the exception that it allows an external 10 Kohm resistor in series with each ARINC input without affecting the ARINC input thresholds. The product is especially useful in applications where lightning protection circuitry is also required. In addition, the test inputs force both of the outputs to zero instead of open circuit. The analog/digital CMOS product requires only a 5 volt supply and is available in a 8-pin SOIC package. Each side of the ARINC bus must be connected through a 10 Kohm series resistor in order for the chip to detect the correct ARINC levels. The typical 10 volt differential signal is translated and input to a window comparator and latch. The comparator levels are set so that with the external 10 Kohm resistors they are just below the standard 6.5 volt minimum ARINC data threshold and just above the standard 2.5 volt maximum ARINC null threshold. The TESTA and TESTB inputs bypass the analog inputs for testing purposes. Also if TESTA and TESTB are both taken high, the digital outputs are forced to zero.

The nominal settings correspond to a One/Zero amplitude of 6.0V and a Null amplitude of 3.3V. 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 35KW of resistance of which 25KW is internal to the chip. The series resistance is connected to level translators whose resistance to Ground is typically 10KW. In order for the voltage translation not to be adversely affected, an external 10KW series resister must be added to each ARINC input. The HI-8588-10 device is typically chosen for applications where external series resistors are required in its lightning protection circuitry. 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. Unlike the HI-8588, if TESTA and TESTB are both One, the HI-8588-10 outputs are pulled low instead of being tri-stated. This allows the digital outputs of a transmitter to be connected to the test inputs through control logic for 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 TEST ONE S Q ROUTA LATCH TESTA R TESTB RINA RINB ESD PROTECTION AND TRANSLATION NULL TEST ZERO S Q ROUTB LATCH TESTA R TESTB NULL FIGURE 1 - RECEIVER BLOCK DIAGRAM 5V 1 HARDWIRE OR DRIVE FROM LOGIC 2 { 8 10KW APPLICATION INFORMATION 4 TESTA ROUTA TESTB ROUTB 6 7 3 10KW RXD1 RXD0 HI-8588-10 RINA ARINC Channel Figure 2 shows a possible application of the HI-8588-10 interfacing an ARINC receive channel to the HI-6010 which in turn interfaces to an 8-bit bus.
