High speed operation - 40K baud, 200ns strobes
Master reset - resets all status outputs
Tri-state outputs - bus structure oriented
Low power requirements
Input protected - eliminates handling problems
Plastic DIP package for easy board insertion
Overview
The Universal Asynchronous Receiver/Transmitter is an MOS/LSI monolithic circuit that performs all the receiving and transmitting functions associated with asynchronous data communications. This circuit is fabricated using SMC's P-channel low voltage oxide0nitride technology. The duplex mode, baud rate, data word length, parity mode, and number of stop bits are independently programmable through the use of external controls. There may be 5, 6, 7, or 8 data bits, odd/even or no parity, and 1, or 2 stop bits or 1.5 stop bits when utilizing a 5-bit code from the COM2017.
