Description
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.
