74AHCT1G07GW,125

Buffers, Drivers, Receivers, Transceivers Overview

The NXP USA Inc. 74AHCT1G07GW,125 is a single non-inverting buffer with an open-drain output, housed in a TSSOP-5 (SOT353-1) package. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device supports industrial temperature ranges from -40 °C to +125 °C. Static characteristics include a maximum input leakage current of 2.0 μA at -40 °C to +125 °C and a low-level output voltage of 0.55 V max at 8.0 mA drive. Dynamic performance specifies propagation delays between 1.0 ns and 7.0 ns depending on load capacitance and voltage.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '125' against official Nexperia documentation to confirm standard packaging details. Confirm that the TSSOP-5 package variant matches the required footprint dimensions. Ensure the component status is active for new designs, as older revisions may have different availability or specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an open-drain output is required for interfacing with higher voltage buses or implementing wired logic functions. The AHCT series ensures TTL-compatible input switching levels while maintaining CMOS performance. Verify that the application does not require a push-pull output stage, as this device cannot source current actively.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC/AHCT family of high-speed silicon-gate CMOS logic devices. It provides a single buffer function in a compact surface-mount package. The device is pin-compatible with other small-outline logic packages, facilitating space-constrained PCB layouts for portable and industrial electronics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the 74AHC1G07GV (SC-74A package) and 74AHC1G07GZ (XSON5 package). Other manufacturers offer equivalent open-drain buffers such as the SN74LVC1G07, but verify input/output voltage tolerances and package dimensions before substitution.

Buffers, Drivers, Receivers, Transceivers FAQ

Can the 74AHCT1G07GW,125 be used for bidirectional level shifting?

No, this device is a unidirectional buffer. For bidirectional level shifting, a dedicated translator like the 74LV1T34 is required.

What happens if the input voltage exceeds the supply voltage?

The inputs are overvoltage tolerant up to 5.5 V, allowing safe operation even if the input signal is higher than the VCC supply, provided it does not exceed the absolute maximum rating.
