SN74LVC1T45DBVR TI 1.65V to 5.5V Single Bit Dual Supply Bus Transceiver IC - SOT-23-6 Package

SN74LVC1T45DBVR 1.65V to 5.5V Single Bit Dual Supply Bus Transceiver IC - SOT-23-6 Package is a high-speed, single-bit dual-supply bus transceiver with configurable bidirectional voltage translation. It supports independent supply voltages from 1.65V to 5.5V on both ports, making it ideal for level shifting between 1.8V, 2.5V, 3.3V, and 5V logic systems. With configurable direction control, partial power-down support, and low power consumption, it is widely used in microcontroller, FPGA, sensor, and communication interfaces.
