If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/Distributors for availability and specifications.

Note: Absolute maximum ratings are those values beyond which the safety of the device cannot be guaranteed. Continuous operation at these limits is not intended; operation should be limited to those conditions specified under DC Electrical Characteristics.

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 buffers, 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-STATEÉ 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 standard INS8212 and DP8212 devices.

For military applications, the MM82PC12 is available with class B screening in accordance with method 5004 of MILSTD-883.
