ID82C82

Overview

The ID82C82 is a CMOS octal latching bus driver manufactured by Renesas Electronics Corporation. It provides an eight-bit parallel latch and buffer interface, compatible with bipolar 8282 designs. The device features three-state non-inverting outputs and gated inputs to reduce operating power and eliminate pull-up resistors. It operates on a single 5V supply with a maximum propagation delay of 35ns. The industrial temperature grade (I82C82) supports operation from -40°C to +85°C. It is housed in a 20-pin package.

Feature Summary

• Full eight-bit parallel latching buffer functionality
• Three-state non-inverting outputs for system interfacing
• Gated inputs to reduce power consumption
• Compatible with standard microprocessor systems

Applications

• Microprocessor data bus buffering
• Parallel latching applications
• Industrial control systems requiring wide temperature ranges

Procurement Notes

Verify the specific suffix designation, as the ID prefix typically indicates military or extended temperature grades compared to commercial variants. Confirm RoHS compliance status, as older CMOS logic families may have leaded options. Check current production status, as this component series may be subject to discontinuation notices. Ensure the required package type matches the design footprint.

Selection Notes

Select the ID82C82 when an octal latching buffer with three-state outputs is required for 5V CMOS systems. Compare against the commercial C82C82 if the application operates within 0°C to +70°C. Verify that the 35ns propagation delay meets the system timing requirements. Ensure the 20-pin package configuration aligns with the PCB layout constraints.

Part Context

The ID82C82 belongs to the Intersil/Renesas 82C82 family of high-performance CMOS octal latching buffers. This series is designed to replace older bipolar 8282 drivers while offering lower power consumption. The ID variant specifically denotes the industrial temperature range extension, distinguishing it from commercial and military temperature grades within the same functional family.

Replacement Considerations

The C82C82 serves as the commercial temperature equivalent. For bipolar replacements, the 8282 is functionally compatible but consumes more power. Verify pinout compatibility before substituting.
