HI-8588 August 2006 ARINC 429 LINE RECEIVER PIN CONFIGURATION VCC - 1 TESTA - 2 RINB - 3 RINA - 4 8 - TESTB DESCRIPTION The HI-8588 is an ARINC 429 bus interface receiver and is available in a SO 8 pin package. The technology is analog/digital CMOS. The circuitry requires only a 5 volt supply. The ARINC bus can be connected directly to the chip. The typical 10 volt differential signal is translated and input to a window comparator and latch. The comparator levels 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 for testing purposes. Also if TESTA and TESTB are both taken high, the analog powers down and the digital outputs tristate allowing wire-or possibilities. Please refer to the HI-8588-10 for applications where an external resistance in series with the ARINC inputs is required for lightning protection or when the digital outputs need to be a logic zero rather than open circuit when TESTA and TESTB are both high. See Holt Application Note AN-300 for more information on lightning protection. 8588PS 7 - ROUTB 6 - ROUTA 5 - GND 8 - PIN PLASTIC NARROW BODY SOIC SUPPLY VOLTAGES vcc = 5.0V ± 5% FUNCTION TABLE RECEIVER RINA -1.25V to 1.25V -3.25V to -6.5V RINB -1.25V to 1.25V 3.25V to 6.5V -3.25V to -6.5V X X X TESTA 0 0 0 0 1 1 TESTB 0 0 0 1 0 1 ROUTA ROUTB 0 0 1 0 1 HI-Z 0 1 0 1 0 HI-Z FEATURES 3.25V to 6.5V X ! ! ! ! !

C) HOLT INTEGRATED CIRCUITS www.holtic.com 08/06 HI-8588 FUNCTIONAL DESCRIPTION RECEIVER 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 have series resistors, typically 35K ohms. They connect to level translators whose resistance to Ground is typically 10K ohms. Therefore, any series resistance added to the inputs will affect the voltage translation. 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 VCC and Ground. The nominal settings correspond to a One/Zero amplitude of 6.0V and a Null amplitude of 3.3V. 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, then the receiver is powered down and the output pins float. The powerdown does not disconnect the internal resistors at the ARINC input.
