The HD74LV2GT157A has 2channel multiplexer in 8 pin package. The input protection circuitry on this device allows over voltage tolerance on the input, allowing the device to be used as a logiclevel translator from 3.0 V CMOS Logic to 5.0 V CMOS Logic or from 1.8 V CMOS logic to 3.0 V CMOS Logic while operating at the high-voltage power supply. Low voltage and high-speed operation is suitable for the battery powered products (e.g., notebook computers), and the low power consumption extends the battery life.
