CDP6402D

CMOS通用异步接收器/发送器（ UART ） CMOS Universal Asynchronous Receiver/Transmitter UART

Description

The CDP6402 and CDP6402C are silicon gate CMOS Universal Asynchronous Receiver/Transmitter UART circuits for interfacing computers or microprocessors to asynchronous serial data channels. They are designed to provide the necessary formatting and control for interfacing between serial and parallel data channels. The receiver converts serial start, data, parity, and stop bits to parallel data verifying proper code transmission, parity and stop bits. The transmitter converts parallel data into serial form and automatically adds start parity and stop bits.
