100122DCQR

Overview

The 100122DCQR is a non-inverting buffer integrated circuit manufactured by National Semiconductor. It features a single element with nine bits per element, providing parallel signal buffering capabilities. The device is housed in a 24-CDIP package with a width of 0.600 inches (15.24mm). It operates within a temperature range of 0°C to 85°C and is designed for through-hole mounting. This component belongs to the 100K series logic family.

Feature Summary

• Non-inverting signal buffering functionality
• Nine-bit parallel output capability per element
• Through-hole compatible 24-pin ceramic dual in-line package

Applications

• Parallel data bus buffering
• Signal line isolation in digital systems
• Logic level translation interfaces

Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, as TI acquired NS. Confirm the package type is strictly 24-CDIP and not a plastic variant. Ensure the operating temperature range matches industrial standards if required. Check for authenticity markers on the ceramic package. Cross-reference the full part number including suffixes against official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a high-density, non-inverting buffer is required for parallel data paths. The 24-CDIP package suits legacy or high-reliability through-hole designs. Consider the 100K series speed characteristics relative to system timing requirements. Evaluate the thermal performance within the specified 0°C to 85°C range for the intended environment.

Part Context

This part belongs to the National Semiconductor 100K series of logic devices. These components are known for their compatibility with standard TTL logic levels while offering improved performance over earlier generations. The 100122 specifically addresses the need for multi-bit buffering in compact DIP packages, serving as a bridge between complex logic circuits and peripheral interfaces.

Replacement Considerations

Direct substitutes may include other 9-bit non-inverting buffers in 24-CDIP packages from the same logic family. Verify pinout compatibility before substitution. Generic equivalents might exist but require careful electrical parameter matching.
