Standard Microsystems COM1553A
The COM 1553A SMART® (Synchronous Mode Avionics Receiver/Transmitter) is a special purpose COPLAMOS N-Channel MaS/LSI device designed to provide the interface between a parallel 8-bit bus and a MIL-STD1553A serial bit stream. The COM 1553A is a double buffered serial/parallel and parallel/serial converter providing all of the "hand shaking" required between a Manchester decoder/ encoder and a microprocessor as well as the protocol handling for both a MIL-STD-1553 bus controller and remote terminal.| Part No. | COM1553A |
