MM82PC12 8-Bit InputOutput Port

General Description

The MM82PC12 is a microCMOS 8-bit inputoutput port

contained in a standard 24-pin dual-in-line package The

MM82PC12 can be used to implement latches gated buff-

ers or multiplexers Thus all of the major peripheral and

inputoutput functions of a microcomputer system can be

implemented with this device

The MM82PC12 includes an 8-bit latch with TRI-STATE

output buffers and device selection and control logic Also

included is a service request flip-flop for the generation and

control of interrupts to the microprocessor

The MM82PC12 is pinout and function compatible with stan-

dard INS8212 and DP8212 devices

For military applications the MM82PC12 is available with

class B screening in accordance with method 5004 of MIL-

STD-883
