This bus buffer gate is designed for 1.65-V to 5.5-V VCC operation.

The SN74LVC1G125 device is a single line driver with a 3-state output. The output is disabled when the output-enable (OE) input is high.

The CMOS device has high output drive while maintaining low static power dissipation over a broad VCC operating range.

The SN74LVC1G125 device is available in a variety of packages including the ultra-small DPW package with a body size of 0.8 mm × 0.8 mm.
