Overview
The SN74LVC1G125DBVR, produced by Texas Instruments, is a single bus buffer gate with a 3-state output. This CMOS device is designed for operation over a wide voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It features a single line driver with output enable control, allowing the output to be disabled when the output-enable (OE) input is high. The device is known for its high output drive while maintaining low static power dissipation, making it suitable for power-sensitive designs. It is available in several package options, including the ultra-small DPW package with a body size of 0.8 mm × 0.8 mm and the SOT-23 (DBV) package with 5 pins.
