MM82PC12 8-Bit Input/Output Port
General Description
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.
The MM82PC12 includes an 8-bit latch with TRI-STATE
é
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.
