74AHC125D,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC125D,118 is a quad buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 5.5 V and utilizes an SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm. The device supports an ambient temperature range from -40 °C to +125 °C. Inputs are overvoltage tolerant up to 5.5 V, enabling use as translators in mixed-voltage environments. Static characteristics include a maximum input leakage current of 2.0 μA at -40 °C to +125 °C when VCC is 5.5 V.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring four buffered channels with independent control. The wide supply voltage range accommodates various logic families. Ensure the design accounts for the specified power dissipation derating curves above 100 °C for the SO14 package to maintain reliability under thermal stress.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC family of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with other industry-standard quad buffers but offers specific overvoltage tolerance and ESD protection characteristics defined by Nexperia's manufacturing processes. The 'D' designation indicates the SO14 surface-mount package variant.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for equivalent parts such as the 74AHCT125D,118 if TTL-compatible input levels are required instead of CMOS levels. Verify that any substitute maintains the same SO14 package dimensions and pinout configuration to ensure mechanical compatibility.
