SN74LVC125ARGYRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125ARGYRG4 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 supports an operating temperature range of -40°C to 85°C and -40°C to 125°C. Inputs accept voltages up to 5.5V, enabling translation between 3.3V and 5V systems. It is housed in a 14-pin VQFN package (RGY) measuring 3.50mm x 3.50mm.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as defined in the manufacturer's documentation. Confirm the RGY package variant matches the required thermal and mechanical constraints for the target PCB layout. Ensure the moisture sensitivity level rating aligns with the assembly process capabilities.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad bus buffer with independent control is required for 1.65V to 3.6V logic families. The 5.5V tolerant inputs make it suitable for interfacing with legacy 5V devices in mixed-signal designs. Consider the VQFN package size and thermal resistance values if high-density mounting or elevated temperature operation is anticipated.

Buffers, Drivers, Receivers, Transceivers FAQ

How should unused inputs be handled?

All unused inputs must be connected to either VCC or GND to prevent undefined operational states and excessive current consumption.

What is the function of the OE pin?

The Output Enable (OE) pin disables the respective buffer output when held high, placing the output in a high-impedance state. When low, the buffer passes data from input A to output Y.
