The SN74LVC2T45DCTT is a Voltage Levels Dual Bit Dual Supply Transceiver manufactured by Texas Instruments. It is used to transfer digital data between two circuits in a voltage translation mode while providing High-Level noise Immunty. This device has two separate supply terminals, allowing it to operate from a single supply voltage or different supply voltages. It can operate over a wide range voltage range, including Industrial temperature range, and is designed to tolerate inputs and outputs from 0.0 to 5.5V. The device has low power consumption, making it an ideal choice for battery-powered applications. It also features enable/disable control and automatic direction sensing, allowing it to automatically adjust its output signal levels, based on the input from the other connected circuit.
