SN74LVC125AD

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125AD 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 5V systems while operating at lower voltages. It is housed in a 14-pin SOIC package and supports an operating temperature range from -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm the exact carrier type and quantity. Ensure the selected variant matches the required thermal resistance and moisture sensitivity level for the intended assembly process. Cross-reference the datasheet revision history to confirm the active production status and any recent updates to electrical characteristics or packaging dimensions.

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. The wide input voltage tolerance allows interfacing between 5V logic sources and 3.3V or lower voltage buses. Consider the SOIC-14 package constraints regarding board space and thermal dissipation requirements relative to other available package options like SSOP or VQFN.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVC125A family of quadruple bus buffers. The 'D' suffix specifically denotes the 14-pin Small Outline Integrated Circuit (SOIC) package variant. This family provides balanced output drive and is designed for applications requiring signal buffering and translation between different voltage domains within digital communication systems.

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 maximum input voltage supported?

Inputs can be driven from either 3.3V or 5V devices, accepting voltages up to 5.5V regardless of the VCC supply level.
