74AHCT2G125DC,125

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT2G125DC,125 is a dual buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes the VSSOP8 package (SOT765-1). The device provides TTL input switching levels with overvoltage tolerant inputs up to 5.5 V, enabling use in mixed-voltage environments. It exhibits symmetrical output impedance, balanced propagation delays, and high noise immunity.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm RoHS compliance status and REACH registration details directly with the manufacturer or authorized distributors prior to procurement. Ensure the component version aligns with current production specifications to avoid obsolescence risks during design-in phases.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible logic levels are required alongside three-state bus control capabilities. The overvoltage tolerant inputs allow interfacing with 5.5 V signals while operating at standard 5 V logic levels. Verify that the VSSOP8 package dimensions fit the target PCB layout constraints and thermal requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC(A)HCT2G series of dual logic gates designed for space-constrained applications. The 'DC' suffix indicates the VSSOP8 plastic very thin shrink small outline package. It is functionally compatible with other industry-standard 74AHCT logic families but offers reduced footprint and improved performance characteristics.
