SN74LVC1G125-Q1 Automotive Single Bus Buffer Gate Texas Instruments SN74LVC1G125-Q1 Automotive Catalog Single Bus Buffer Gate is designed for 1.65V to 5.5V VCC operation. The SN74LVC1G125-Q1 buffer gate 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 a high output drive while maintaining low static power dissipation over a broad VCC operating range.
