... ARINC 429 communication protocol. Additional interface circuitry such as the Holt HI-8585, HI-8586 or HI-3182 is required to translate the 5 volt logic outputs to ARINC 429 drive levels. The 16-bit parallel data bus exchanges the 32-bit ARINC data word in two steps when either loading the transmitter or interrogating the receivers ...

... Latch enable for byte 1 entered from data bus to transmitter FIFO. Latch enable for byte 2 entered from data bus to transmitter FIFO. Must follow Transmitter ready flag. Goes low when ARINC word loaded into FIFO. Goes high after transmission and FIFO empty. "ONES" data output from transmitter. ...

... This option is especially useful in applications where lightning protection circuitry is also required. Each side of the ARINC bus must be connected through a 10K to 15K ohm series resistor in order for the chip to detect the correct ARINC COMPARATORS levels. The typical 10 volt differential signal is translated and input to a window comparator and latch ...

... When the receive sig- nal is outside the differential voltage range defined for any shift register, a low bit is clocked. Only one shift register can clock a high bit for any given sample. All three registers clock low bits if the differential input voltage is between de- fined state voltage bands ...
