TXS0102DCTR TI 2-Bit Bidirectional Voltage Level Translator VSSOP-8

The TXS0102DCTR from Texas Instruments is a 2-bit bidirectional voltage-level translator designed for interfacing between different voltage domains in digital systems. It supports both push-pull and open-drain applications and provides automatic bidirectional signal translation without requiring a direction-control signal.

The device supports voltage translation between 1.65V to 3.6V on the A port and 2.3V to 5.5V on the B port when VCCA is equal to or lower than VCCB. It provides a flexible solution for connecting low-voltage processors, microcontrollers, sensors, and communication interfaces with higher-voltage logic systems.

TXS0102DCTR supports data rates up to 24Mbps for push-pull signals and up to 2Mbps for open-drain signals. The device integrates automatic direction sensing, allowing seamless bidirectional communication for interfaces such as I²C, GPIO, UART, and other low-speed digital communication systems.

The device includes power-off protection through the Ioff feature, allowing operation in partial power-down conditions. It also supports flexible power-up sequencing, meaning either supply voltage can ramp first without affecting device reliability. The TXS0102DCTR is supplied in a compact 8-pin VSSOP package and operates from -40°C to +85°C.

Typical applications include voltage translation between MCUs and peripherals, IoT devices, portable electronics, communication modules, sensor systems, and embedded control equipment.
