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.
