SN74LVC125APWT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125APWT 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 and -40°C to 125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features four independent line drivers with 3-state outputs controlled by separate OE inputs.
• Inputs are overvoltage tolerant, accepting voltages up to 5.5V regardless of the VCC level.
• Designed for low-power operation within a wide supply voltage range of 1.65V to 3.6V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-14 package and 'T' indicates small tape-and-reel packaging (250 units). Confirm RoHS compliance and lead finish details via the manufacturer's latest Package Option Addendum. Ensure the selected variant matches the required thermal resistance and moisture sensitivity level for your assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quadruple non-inverting buffer with high-drive capability and 3-state control is required. It is suitable for mixed-voltage environments due to its 5.5V input tolerance. Consider the TSSOP-14 package constraints and ensure unused inputs are tied to VCC or GND to prevent undefined states during operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC125A family of quadruple bus buffers. The 'P' denotes the TSSOP package type, while 'W' specifies the tube carrier option in some contexts, though 'T' typically indicates tape and reel. It is part of Texas Instruments' LVC logic series designed for low-voltage CMOS applications.

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 pull-up resistor.

Can this device translate between 3.3V and 5V logic levels?

Yes, the inputs accept voltages up to 5.5V, allowing the device to function as a translator in mixed 3.3V/5V system environments.
