The CD82C83H is an 8-bit I/O port manufactured by Intersil Corporation. Categorized as 'END-OF-LIFE', it is an obsolete component. The CD82C83H is a CMOS octal latch designed for use as a general-purpose I/O port in microprocessor-based systems.

I/O ports like the CD82C83H provide a means for microprocessors to communicate with external devices and peripherals, enabling data transfer and control signals.

Applications

• Originally used in early computer systems for I/O control.
• Industrial control systems.
• Data acquisition systems.

Features

• 8-bit data bus: Provides parallel data transfer between the microprocessor and peripherals.
• CMOS technology: Low power consumption and high noise immunity.
• Three-state outputs: Allows multiple devices to share the same data bus.
• High output drive capability: Can drive multiple TTL loads.
• Transparent latch operation: Data passes through the latch when enabled.

Benefits

• Simplified I/O interfacing for microprocessors.
• Reduced power consumption compared to bipolar devices.
• Improved noise immunity.
• Compatibility with standard TTL logic levels.

The CD82C83H is typically packaged in a DIP package. Details and datasheets may be difficult to find due to the product's end-of-life status.
