100112DCQR

Overview

The 100112DCQR is a buffer and inverter component from the National Semiconductor F100112 series. It features a single element with four bits per element, providing both inverting and non-inverting logic functions. The device utilizes a 3-state output configuration to facilitate bus-oriented connections. It is housed in a 24-pin Ceramic Dual In-Line Package (CDIP) with a standard 0.600-inch width. This integrated circuit is designed for high-performance logic applications requiring signal buffering and level shifting capabilities.

Feature Summary

• Provides simultaneous inverting and non-inverting buffer functions within a single package
• Features 3-state outputs to support efficient bus-oriented system architectures
• Constructed in a robust ceramic dual in-line package suitable for demanding environments

Applications

• High-speed data handling systems
• Logic level shifting circuits
• Bus-oriented digital designs

Procurement Notes

Verify the specific manufacturer source, as National Semiconductor's logic assets were acquired by Texas Instruments. Confirm that the part number corresponds to the original National Semiconductor fabrication rather than a TI rebranding or equivalent replacement. Ensure the 24-CDIP package dimensions match your board layout requirements before procurement.

Selection Notes

Select this component when a single IC must provide both buffered and inverted signals for a 4-bit wide bus. The 3-state capability allows multiple devices to share a common data line without interference. Consider the ceramic package for thermal stability and reliability in industrial or military-grade applications where plastic packages may be insufficient.

Part Context

This device belongs to the F100112 family of high-speed CMOS logic buffers. The F100 series was widely used in complex digital systems requiring precise timing and signal integrity. As an older component, it represents legacy technology often found in existing industrial control systems or specialized instrumentation equipment.

Replacement Considerations

Check for equivalents from Texas Instruments, which acquired National Semiconductor's logic business. Verify pin compatibility and electrical characteristics against modern replacements if sourcing new units is difficult.
