74H10DC

Overview

The National Semiconductor 74H10DC is a high-speed CMOS logic device belonging to the 74H series. It functions as a triple 3-input NAND gate, providing three independent logic gates within a single integrated circuit package. The component is designed for digital signal processing applications requiring fast switching speeds and low power consumption typical of CMOS technology. It operates with a standard supply voltage range and features standard TTL-compatible inputs, allowing it to interface directly with other logic families in mixed-technology systems.

Feature Summary

• Triple 3-input NAND logic configuration
• High-speed CMOS technology implementation
• TTL-compatible input levels

Applications

• Digital logic control circuits
• Signal gating and masking operations
• General-purpose combinatorial logic design

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix 'DC' matches the required ceramic DIP package variant. Confirm RoHS compliance status if required for modern manufacturing standards, as older stock may differ from current production runs.

Selection Notes

Select this component when a triple 3-input NAND function is required in a high-speed environment. Compare against the 74HC10 or 74HCT10 variants if lower power consumption or different voltage compatibility is needed. Verify package availability, as the ceramic DIP option may have limited long-term supply compared to plastic equivalents.

Part Context

This part belongs to the 74H series of high-speed CMOS logic devices. This family offers performance comparable to the older 74S TTL series but with significantly reduced power dissipation. The 74H series is characterized by its speed-power product optimization, making it suitable for battery-operated applications where speed is critical.

Replacement Considerations

Check for direct equivalents such as the SN74H10N (plastic DIP) or the 74LS10 (TTL) if voltage levels allow. Verify pinout compatibility before substituting with generic 74H10 parts from other manufacturers.
