SN74AHCT00NG4

Overview

The SN74AHCT00NG4 is a quadruple 2-input positive-NAND gate from the Texas Instruments SN74AHCT00 series. It operates within a supply voltage range of 4.5 V to 5.5 V and features low output currents of 8 mA for both high and low states. The device exhibits a propagation delay of 5.5 ns and functions reliably across an extended temperature range from -55°C to +125°C. Packaged in a standard 14-pin DIP configuration, it provides robust digital logic performance suitable for demanding industrial environments.

Feature Summary

• Provides four independent 2-input NAND logic gates in a single package
• Compatible with standard CMOS logic families through HCT input structures
• Engineered for extended industrial temperature operation up to 125°C

Applications

• Industrial control systems requiring wide temperature tolerance
• General-purpose digital logic processing circuits
• Signal gating and switching applications in harsh environments

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free packaging compliance when sourcing. Confirm that the 'N' designation corresponds to the PDIP-14 through-hole package variant. Ensure the component meets RoHS standards required for your assembly process. Cross-reference the manufacturer datasheet for exact pinout definitions before integration into PCB layouts.

Selection Notes

Select this component when a quad NAND gate is required for 5V logic systems operating in extreme thermal conditions. The AHCT series ensures compatibility with HC/TTL inputs while maintaining CMOS noise immunity. Consider the DIP-14 package only if through-hole mounting is necessary for mechanical stability or prototyping purposes.

Part Context

This part belongs to the SN74AHCT00 family of high-speed CMOS logic devices. The 'HCT' suffix denotes compatibility with TTL-compatible inputs, allowing direct interfacing with legacy logic families. The 'G4' suffix typically signifies environmental compliance, specifically lead-free manufacturing processes aligned with modern regulatory standards.

Replacement Considerations

Direct replacements include SN74AHCT00N and SN74AHCT00DR. Verify package compatibility as DR uses SOIC-14. Alternative series like SN74HC00 offer similar functionality but may differ in input threshold voltages and drive strength characteristics.
