74AHCT2G126DC,125

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT2G126DC,125 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 accepts TTL input levels. The device utilizes a VSSOP8 plastic very thin shrink small outline package (SOT765-1) with eight leads and a body width of 2.3 mm. It supports an ambient temperature range from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible input thresholds are required alongside a wide operating voltage range. The VSSOP8 package offers a compact footprint suitable for space-constrained designs. Ensure the application requires three-state control via active HIGH enable inputs rather than active LOW configurations found in other variants.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC/AHCT family of high-speed Si-gate CMOS logic devices. The AHCT variant specifically bridges CMOS output performance with TTL input compatibility. It is part of a series offering dual-functionality in minimal packages, designed for applications demanding balanced propagation delays and low static power consumption across industrial temperature ranges.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT2G126DP serves as a pin-compatible alternative utilizing the TSSOP8 package instead of VSSOP8. Designers must verify package dimensions and thermal characteristics when substituting between these form factors.

Buffers, Drivers, Receivers, Transceivers FAQ

What determines the input logic level type for this device?

The 'AHCT' designation indicates that the device uses TTL input switching levels, distinguishing it from the 'AHC' variant which uses CMOS levels.

How is the three-state output controlled?

The outputs assume a high-impedance OFF-state when the output enable inputs (nOE) are LOW. When nOE is HIGH, the buffers transmit the input data to the outputs.
