SN74LVC125APW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125APW 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 3.3V or 5V driving devices. It is housed in a 14-pin TSSOP package and supports an operating temperature range from -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features four independent line drivers with 3-state outputs controlled by separate OE inputs.
• Inputs are tolerant to 5.5V signals, enabling use as a translator in mixed 3.3V/5V systems.
• Designed for low-voltage operation ranging from 1.65V to 3.6V.

• Optical modules
• Telecom base band units

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the 14-pin TSSOP package configuration. Confirm that the required operating temperature range aligns with the standard industrial specification (-40°C to 85°C) rather than the extended military grade (-40°C to 125°C). Ensure design requirements match the LVC logic family voltage levels.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quadruple non-inverting buffer with high-impedance states is required. It is suitable for applications needing voltage translation between 3.3V and 5V domains due to its overvoltage-tolerant inputs. Consider the TSSOP package constraints regarding thermal dissipation and board space availability during integration.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC125A series of quadruple bus buffers. The 'P' indicates the TSSOP package type, while 'W' specifies the tube carrier option. It is part of the broader LVC logic family designed for low-voltage CMOS applications requiring high drive capability and fast switching speeds.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle power-up conditions?

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