DESCRIPTION

The HI-1575 is a low power CMOS dual transceiver with on-chip Manchester II Encoder and dual Decoder designed to meet the requirements of the MIL-STD-1553 specification. The part acts as a Smart Transceiver, allowing users to transmit and receive properly encoded MIL-STD-1553 Command and Data words between a 16-bit host processor and dual MIL-STD-1553 data buses.

A single write cycle is used to transfer a word to the HI-1575, which encodes the data, adds the selected Sync and Parity bits, and transmits the word on the chosen MIL-STD-1553 data bus. Complete MIL-STD-1553 messages may be transmitted by executing multiple write cycles to the device.
