Overview
The SN74LV1T34DCKRG4, produced by Texas Instruments, is a single power supply single buffer gate CMOS logic level shifter. This device is part of the LVxT family of logic devices, designed for voltage translation applications across a wide range of voltage levels. It operates with a single supply voltage and supports translation between 1.8-V, 2.5-V, 3.3-V, and 5-V CMOS levels. The device is particularly useful in industrial, portable, telecom, and automotive applications due to its ability to handle various voltage levels and its robust operating temperature range of –40°C to +125°C.
