TXB0106

The Texas Instruments TXB0106 is a 6-bit, noninverting, bidirectional voltage-level translator designed for universal low-voltage translation. It features two separate configurable power-supply rails, with the A port tracking VCCA (1.2V to 3.6V) and the B port tracking VCCB (1.65V to 5.5V), ensuring VCCA does not exceed VCCB. This device offers auto-direction sensing and includes features like VCC isolation, where all outputs go to a high-impedance state if either VCC input is at GND.

Key electrical specifications include a maximum data rate of 100 Mbps and a typical propagation delay of 6 ns. The device operates within an environmental temperature range of -40°C to 85°C and has a low maximum supply current of 0.039mA. ESD protection is robust, exceeding AEC-Q100 standards, with up to 2000V HBM on the A port and ±10kV HBM on the B port.

The TXB0106 is available in TSSOP and WQFN packages, both with 16 pins. The TSSOP package has a body size of 5.00mm x 4.40mm, while the WQFN package measures 3.50mm x 2.50mm. The output-enable (OE) input circuit is referenced to VCCA, and the device supports partial-power-down operation using Ioff circuitry to prevent damaging current backflow when powered down.

Applications for the TXB0106 include heating and cooling systems, telematics, and radar. Its bidirectional translation capability makes it suitable for interfaces like GPIO, I2S, JTAG, PCM, SPI, and UART.
