The TXS0102DQMR from Texas Instruments is a 2-bit non-inverting bidirectional voltage-level translator designed to bridge logic signals between mixed-voltage systems. Its automatic direction-sensing architecture eliminates the need for a dedicated direction-control signal, allowing each channel to independently transfer data in either direction.
The device supports 1.65V to 3.6V on the A port and 2.3V to 5.5V on the B port, with VCCA required to be less than or equal to VCCB. It supports both open-drain and push-pull signals, with maximum data rates of 24Mbps for push-pull operation and 2Mbps for open-drain applications.
The TXS0102 uses an N-channel pass-gate architecture with integrated edge-rate accelerators and 10kΩ internal pull-up resistors, making it particularly suitable for open-drain interfaces such as I²C and SMBus while also supporting push-pull CMOS signals. An Output Enable input places all I/O pins into a high-impedance state when disabled, while VCC isolation and Ioff partial-power-down support improve behavior during power-down conditions.
The TXS0102DQMR is supplied in a compact 8-pin X2SON (DQM) package measuring approximately 1.8 × 1.2 mm with a maximum height of about 0.4 mm. It operates from -40°C to +85°C and is supplied in 3000-piece tape-and-reel packaging. TI currently lists the part as ACTIVE.
