HS-82C12RH

Radiation Hardened 8-Bit Input/Output

Port

The Intersil HS-82C12RH is a radiation hardened 8-bit

input/output port designed for use with the HS-80C85RH

radiation hardened microprocessor. It is manufactured using

a self-aligned, junction-isolated EPI-CMOS process and

features three-state output buffers and device selection and

control logic. A service request flip-flop is included for the

generation and control of interrupts to the microprocessor.

The device can be used in implement many of the peripheral

and input/output functions of a microcomputer system. The

HS-82C12RH is pinout- and function- compatible with

industry-standard 8212 devices.

Specifications for Rad Hard QML devices are controlled

by the Defense Supply Center in Columbus (DSCC). The

SMD numbers listed here must be used when ordering.

Detailed Electrical Specifications for these devices are

contained in SMD 5962-95818. A “hot-link” is provided

on our homepage for downloading.
