Package

The TXS02612RTWR is packaged in a TSSOP (Thin Shrink Small Outline Package) format, specifically a 20-pin TSSOP package.

Pinout

The TXS02612RTWR is a bi-directional level shifter with a total of 12 pins. It is designed to facilitate communication between devices operating at different voltage levels, commonly found in applications involving I²C, SPI, and UART.
The pin functions are as follows:
1. VCCA (Pin 1): Supply voltage for the A side (lower voltage).
2. VCCB (Pin 12): Supply voltage for the B side (higher voltage).
3. GND (Pin 2): Ground connection.
4. A1-A6 (Pins 3, 5, 7, 9, 10, 11): Data input/output pins on the A side.
5. B1-B6 (Pins 4, 6, 8): Data input/output pins on the B side.
The device uses internal circuitry to automatically switch the direction of data flow based on the voltage level, facilitating seamless communication between the two voltage domains.
