74LV125D,118

Buffers, Drivers, Receivers, Transceivers Overview

The 74LV125D,118 is a low-voltage Si-gate CMOS quad buffer and line driver manufactured by NXP USA Inc. It features four non-inverting buffers with three-state outputs controlled by active-low output enable inputs (nOE). The device operates within a supply voltage range of 1.0 V to 5.5 V and accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. It is housed in a 14-lead SOIC package (SOT108-1) and supports operating temperatures from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '118' against current manufacturer documentation to confirm packaging and tape/reel specifications. Confirm RoHS compliance status and REACH registration details directly with NXP or authorized distributors prior to procurement. Ensure the SOIC-14 package variant matches the required PCB footprint dimensions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring wide voltage compatibility and three-state bus management. It serves as a direct functional replacement for 74HC125 and 74HCT125 devices where lower power consumption or broader voltage tolerance is needed. Verify that the input transition rates and load capacitance requirements align with the specified dynamic characteristics for the target operating voltage.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices. It is functionally equivalent to the standard 74HC125 but optimized for operation down to 1.0 V. The 'D' designation indicates the SOIC-14 plastic small outline package, while the ',118' suffix typically denotes the specific reel packaging configuration provided by the manufacturer.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly states the device is pin and function compatible with 74HC125 and 74HCT125. These parts can be substituted if voltage ranges and drive strengths meet the system requirements.
