MM82PC12 8-Bit Input/Output Port

General Description

Features

Drive capabilityÐ150 pF load

The MM82PC12 is a microCMOS 8-bit input/output 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

input/output functions of a microcomputer system can be

implemented with this device.

High noise immunity

Low power dissipation

Full interface to CMOS logic levels

microCMOS technology

TTL drive capability when V

8-bit data latch and buffer

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.

Service request flip-flop for generation and control of

interrupts

1 mA input load current

The MM82PC12 is pinout and function compatible with stan-

dard INS8212 and DP8212 devices.

Reduces system package count by replacing buffers,

latches, and multiplexers in microcomputer systems

For military applications, the MM82PC12 is available with

class B screening in accordance with method 5004 of MIL-

STD-883.
