SN74LVC125ARGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125ARGYR 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-VQFN package (3.5mm x 3.5mm) and supports an operating temperature range of -40°C to 125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'RGYR' corresponds to the VQFN-14 package and tape-and-reel carrier configuration. Confirm that the moisture sensitivity level and peak reflow temperature ratings align with your assembly process requirements. Ensure the component meets RoHS compliance standards as specified in the manufacturer's documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring voltage translation between 3.3V and 5V logic levels. It is suitable for applications needing high-speed buffering with independent channel control. Consider the thermal resistance characteristics of the VQFN package if operating at maximum ambient temperatures or under heavy load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC125A family of quadruple bus buffers. The 'ARGYR' suffix designates the specific 14-pin VQFN package variant with reel packaging. It is part of Texas Instruments' broader LVC logic series designed for low-voltage CMOS applications.

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 input voltage tolerance?

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