74AHCT2G126DC-Q10H

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHCT2G126DC-Q10H is a dual buffer and line driver featuring three-state outputs controlled by active-high output enable inputs (nOE). It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes TTL input switching levels. The device is housed in an 8-lead VSSOP package (SOT765-1) and supports an ambient temperature range from -40 °C to +125 °C. Inputs are overvoltage tolerant up to 5.5 V, facilitating use as translators in mixed-voltage environments.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with the requested package type and qualification grade. Confirm that the component meets the required AEC-Q100 Grade 1 specifications for your intended automotive application before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance characteristics. Ensure the design environment stays within the specified 4.5 V to 5.5 V supply voltage range. Consider the VSSOP package dimensions if board space is constrained, and verify thermal dissipation requirements for operation at elevated temperatures.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC_AHCT2G126-Q100 family of dual buffers. It shares functional similarities with other members like the 74AHC2G126DC-Q100 but differs in input threshold levels, utilizing TTL standards instead of CMOS. The DC suffix indicates the VSSOP8 plastic very thin shrink small outline package variant.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT2G126DP-Q100 serves as a pin-compatible alternative using the TSSOP8 package. Verify package footprint differences during replacement planning.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the input logic level standard for this device?

The 74AHCT2G126DC-Q10H uses TTL input switching levels.

How does the output enable control function?

The outputs are controlled by active-high output enable inputs (nOE); a HIGH signal enables the output while a LOW signal places it in a high-impedance state.
