COM1863 - Universal Asynchronous Receiver/Transmitter

General Description

The Universal Asynchronous Receiver/Transmitter is an MaS/LSI monol ithic circuit that performs all the receiving and transmitting functions associated with asynchronous data communications.

Key Features

  • o Compatible with TR1863 timing o High accuracy 32X clock mode: 48.4375% Receiver Distortion Immunity and improved RDA/ROR operation (COM 8018 only) o High Speed Operation-62.5K baud, 200ns strobes o Single +5V Power Supply o Direct TTL Compatibility-no interfacing circuits required o Input pull-up options: COM 8018 has low current pull-up resistors; COM 1863 has no pull up resistors o Full or Half Duplex Operation-can receive and transmit simultaneously at different baud rates o Fully Double Bu.
