TXS0108E 8-Bit Bidirectional Voltage-Level Translator
8-bit non-inverting bidirectional logic voltage level translator with automatic direction sensing and output enable (OE). Allows seamless communication between mixed-voltage systems (e.g. 1.8V/3.3V microcontrollers and 5V sensors/peripherals) across high-speed I2C, SPI, and UART buses.
