SN74LVC125ADRG3

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125ADRG3 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 SOIC package and supports an operating temperature range from -40°C to 125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DRG3' corresponds to the SOIC-14 package and tape-and-reel carrier configuration. Confirm the component meets RoHS standards and Level-1 moisture sensitivity ratings as specified in the manufacturer's packaging data sheet before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low-voltage operation between 1.65V and 3.6V. The 5.5V tolerant inputs facilitate integration into mixed-voltage environments without external level shifting. Ensure the design accommodates the specified thermal resistance values for the SOIC-14 package under expected ambient conditions.

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 output-enable (OE) input should be tied to VCC through a pull-up resistor.

What is the maximum input voltage tolerance?

The inputs can accept voltages up to 5.5V, allowing them to be driven by either 3.3V or 5V devices regardless of the VCC supply voltage.
