Overview
The SN74LV1T125DBVR, produced by Texas Instruments, is a single power supply single buffer gate with 3-state output. This device belongs to TI's LVxT family of logic devices, which are designed for integrated voltage level translation. It operates over a wide voltage range, supporting 1.8-V, 2.5-V, 3.3-V, and 5-V CMOS levels, making it versatile for various applications. The device features reduced input voltage thresholds and 5.0V tolerant input pins, enabling both up-translation and down-translation of voltage levels. It is particularly useful in industrial, portable, telecom, and automotive applications due to its robust operating temperature range of –40°C to 125°C and high current-drive capability to reduce line reflections and signal distortions.
