2 / 19 page 429D0 (HI-3586 only) 429D1(HI-3586 only) SIGNAL FUNCTION DESCRIPTION NOTE RINB INPUT ARINC receiver negative input. Direct connection to ARINC 429 bus RINB-40 INPUT Alternate ARINC receiver negative input. Requires external 40K ohm resistor MR INPUT Master Reset. A positive pulse clears Receive and Transmit data FIFOs and flags 10K ohm pull-down* SI INPUT SPI interface serial data input 10K ohm pull-down* INPUT Chip select. Data is shifted into SI and out of SO when is low. 10K ohm pull-up* SCK INPUT SPI Clock. Data is shifted into or out of the SPI interface using SCK 10K ohm pull-down* GND POWER Chip 0V supply ACLK INPUT Master timing source for the ARINC 429 receiver and transmitter 10K ohm pull-down* SO OUTPUT SPI interface serial data output RFLAG OUTPUT Goes high when ARINC 429 Receive FIFO is empty (CR15=0), or full (CR15=1) TFLAG OUTPUT Goes high when ARINC 429 Transmit FIFO is empty (CR14=0), or full (CR14=1) V- POWER Minus 5V power supply to ARINC 429 Line Driver (HI-3585 only) BOUT37 OUTPUT ARINC line driver negative output.
