TXB0101 Translators

The TXB "Buffer-type" translators are dual-supply auto direction-sensing devices used to bridge the digital-switching compatibility gap between two different supply-voltages on the same circuit board. These TXB01xx auto-direction level shifters eliminate the requirement of a direction-control signal saving GPIOs on the system processor and simplifying the associated software development. The TXB01xx devices can translate anywhere between 1.2 V and 5.5 V and a have low static power consumption of 5 µA Max. They support partial-power-down mode operation and do not require power-supply sequencing. They also include 15 kV HBM ESD protection, support data rate speeds of up to 100 Mbps, and are optimized for use with "Push-Pull" CMOS drivers.

Auto Direction-Sensing Translators with integrated ESD protection

The integrated 15 kV HBM ESD protection provides designers with a robust system design without having to spend on discrete ESD protection devices. Since the translators are auto-sensing, they do not need a direction control signal to guide the direction of dataflow. This feature saves GPIOs on the processor and also simplifies software control. The low power consumption and small footprints make these devices an ideal choice for use in battery-powered, portable applications. TI's TXB01xx auto-direction sensing level shifters are available in four different bit-widths: 1-bit, 2-bits, 4-bits, and 8-bits.
