Radiation Hardened 8-Bit Input/Output
Port
Features
• Electrically Screened to SMD # 5962-95818
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.
