74AHCT2G08DC,125

Overview

The Nexperia 74AHCT2G08DC,125 is a dual 2-input AND gate implemented in 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-pin VSSOP housing.

Feature Summary

• TTL-compatible input switching levels for direct interfacing with TTL logic systems
• High noise immunity and symmetrical output impedance characteristics
• ESD protection compliant with ANSI/ESDA/JEDEC JS-001 class 2 and JS-002 class C3 standards

Applications

• Digital signal processing circuits requiring TTL-to-CMOS level translation
• Portable battery-powered equipment due to low power dissipation
• Consumer electronics utilizing high-speed logic operations

Procurement Notes

Verify the complete part number including the suffix ,125 to ensure correct packaging configuration. Confirm that the application environment remains within the specified -40 °C to +125 °C operating temperature range. Ensure supply voltage does not exceed the maximum limit of 5.5 V to prevent device damage. Check RoHS compliance status if required by specific regulatory frameworks.

Selection Notes

Select this component when TTL input compatibility is required alongside CMOS performance benefits. The AHCT series is suitable for designs needing operation strictly at 5 V nominal voltage. Consider the VSSOP package dimensions for PCB layout constraints. Verify that the dual gate configuration meets the logical requirements without necessitating additional components.

Part Context

This device belongs to the Nexperia 74AHC(T) family of high-speed Si-gate CMOS logic devices. The AHCT variant specifically bridges the gap between CMOS efficiency and TTL interface requirements. It is designed for applications demanding high speed and low power consumption in compact surface-mount packages.

Replacement Considerations

Publicly confirmed substitute part numbers include 74AHCT2G08DC-Q100H.
