74AHC2G00DC,125

Overview

The Nexperia 74AHC2G00DC,125 is a high-speed Si-gate CMOS dual 2-input NAND gate in an 8-lead VSSOP package (SOT765-1). It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features symmetrical output impedance, balanced propagation delays, and high noise immunity. Static characteristics include input leakage currents up to 2.0 μA at maximum temperature. Dynamic performance specifies propagation delays ranging from 1.0 ns to 10.5 ns depending on load capacitance and voltage.

Feature Summary

• Provides two independent 2-input NAND logic functions within a compact surface-mount package.
• Features symmetrical output impedance and balanced propagation delays for consistent signal timing.
• Includes robust ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model standards.

Applications

• General-purpose digital logic processing
• Signal gating and switching circuits
• Mixed-signal interface buffering

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the DC suffix denotes the VSSOP8 form factor. Confirm that the component status remains active production rather than obsolete or limited availability. Ensure the requested quantity aligns with standard manufacturing reel sizes if applicable. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and current datasheet revision status before finalizing procurement orders.

Selection Notes

Select this component when a dual NAND configuration is required in space-constrained designs utilizing the VSSOP8 footprint. The AHC series offers superior speed compared to standard HC logic while maintaining low power consumption suitable for battery-operated systems. Verify that the system supply voltage falls within the 2.0 V to 5.5 V operational window. Consider the thermal derating requirements if operating near the upper temperature limits of the specified range.

Part Context

This device belongs to the Nexperia 74AHC family of high-speed CMOS logic gates. The 74AHC2G00DC variant specifically utilizes the VSSOP8 package, distinguishing it from other package options like TSSOP8 or XSON available within the same logical family. It serves as a direct replacement for legacy dual NAND gates requiring similar pinouts and electrical characteristics but with improved switching speeds and lower power dissipation profiles.

Replacement Considerations

The 74AHCT2G00DC is a compatible alternative offering TTL-compatible input levels instead of CMOS levels. Designers must verify input voltage thresholds match the source logic family when substituting between AHC and AHCT variants. Other package versions such as the TSSOP8 (74AHC2G00DP) provide identical electrical performance but require different PCB land patterns.

FAQ

What is the difference between the 74AHC2G00 and 74AHCT2G00 input specifications?

The 74AHC2G00 utilizes CMOS input switching levels, whereas the 74AHCT2G00 features TTL input switching levels. Both share the same supply voltage range and output characteristics.

How does the VSSOP8 package affect thermal performance?

The VSSOP8 package has a total power dissipation derating rate of 4.9 mW/K above 99 °C. This linear derating ensures safe operation within the specified temperature range by limiting heat generation relative to ambient conditions.
