74AHC126D,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC126D,118 is a quad buffer and line driver featuring three-state outputs controlled by active-high output enable inputs. It operates within a supply voltage range of 2.0 V to 5.5 V and utilizes the SO14 (SOT108-1) plastic small outline package with a body width of 3.9 mm. The device supports an ambient operating temperature from -40 °C to +125 °C. Inputs are overvoltage tolerant, accepting voltages higher than VCC, which facilitates use as translators in mixed-voltage environments.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Balanced propagation delays across all channels
• All inputs feature Schmitt-trigger action for noise immunity
• Inputs accept voltages exceeding the supply voltage level

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed voltage signal translation
• Bus-oriented communications
• Clock distribution and buffering

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the component status remains active and check for any recent Product Change Notifications regarding marking or assembly updates. Ensure design compliance with absolute maximum ratings to prevent permanent damage during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when CMOS-level input logic compatibility is required alongside high-speed buffering capabilities. The overvoltage-tolerant inputs allow direct interfacing with systems operating at different voltage levels without external protection components. Verify that the thermal dissipation requirements align with the specified derating curves for the SO14 package.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC family of high-speed CMOS logic devices manufactured by Nexperia. It serves as a non-inverting buffer with three-state control, distinct from the 74AHCT variant which accepts TTL-level inputs. The D,118 designation specifically identifies the SO14 surface-mount package version intended for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the output behave when the nOE input is LOW?

When the nOE input is LOW, the outputs assume a high-impedance OFF-state regardless of the data input state.

What is the function of the Schmitt-trigger action on the inputs?

The Schmitt-trigger action ensures clean switching transitions and provides improved noise immunity for the input signals.
