74AHCT2G00DC,125

Overview

The Nexperia 74AHCT2G00DC,125 is a dual 2-input NAND gate integrated circuit manufactured using high-speed silicon-gate CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input switching levels. The device provides symmetrical output impedance with low power dissipation and balanced propagation delays. It supports an operating temperature range from -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Packaged in an 8-VSSOP surface-mount case, it delivers a low-level output current of 8 mA.

Feature Summary

• Provides two independent 2-input NAND logic gates in a compact package
• Features TTL-compatible input switching levels for direct interfacing with TTL systems
• Offers high noise immunity and symmetrical output impedance characteristics
• Includes robust electrostatic discharge protection compliant with industry standards

Applications

• Digital signal processing circuits requiring NAND logic functions
• Microcontroller peripheral interface designs
• General-purpose logic applications in consumer electronics
• Industrial control system logic gating

Procurement Notes

Verify the complete part number including the suffix ,125 to ensure correct packaging configuration. Confirm RoHS compliance status and lead times through authorized distributors. Check for any specific environmental declarations such as REACH or MSL ratings relevant to your assembly process. Ensure the supplier provides official datasheets for technical validation before procurement.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance benefits. The AHCT series bridges the gap between older TTL logic families and modern CMOS technologies. Consider the 8-VSSOP package constraints for PCB layout. Verify that the 4.5 V to 5.5 V supply range matches your system power rails. Evaluate ESD protection requirements against your application environment.

Part Context

This device belongs to the Nexperia 74AHCT family, which combines the speed of AHC logic with the input compatibility of HCT logic. The 74AHCT2G00 specifically denotes a dual NAND gate configuration. The DC suffix indicates the 8-VSSOP package type. The 125 suffix typically refers to the reel size or tape-and-reel specification used by manufacturers for automated assembly processes.

Replacement Considerations

Direct functional equivalents include other 74AHCT2G00 variants from different manufacturers offering identical pinouts and electrical characteristics. Cross-reference with 74AHC2G00 if TTL input compatibility is not strictly required, noting the difference in input voltage thresholds. Verify package dimensions and thermal characteristics when substituting.
