SN74LVC125APWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125APWG4 is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65V to 3.6V and features independent output-enable inputs for each buffer. The device accepts input voltages up to 5.5V, allowing compatibility with mixed 3.3V/5V systems. It is housed in a 14-pin TSSOP package and supports operating temperatures from -40°C to 85°C or -40°C to 125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green manufacturing options as per Texas Instruments standards. Confirm the PW package designation corresponds to the 14-pin Thin Shrink Small Outline Package (TSSOP). Ensure the selected temperature grade matches the required operational environment limits defined in the datasheet specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring bus buffering between logic families operating at different voltage levels, specifically translating between 3.3V and 5V domains. The independent output enables allow precise control over bus contention. Consider the maximum propagation delay and drive current capabilities relative to the load capacitance and signal integrity requirements of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC125A family of quadruple bus buffer gates. The 'PW' suffix identifies the 14-pin TSSOP physical package, while the 'G4' suffix denotes environmental compliance attributes including lead-free finish and RoHS adherence. It is a production-active component within the Texas Instruments logic IC portfolio.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle power-up states?

To ensure the high-impedance state during power up or power down, the OE input should be tied to VCC through a pull-up resistor.

What is the function of the OE pin?

Each output is disabled when the associated output-enable (OE) input is high. When OE is low, the respective gate passes data from the A input to its Y output.
