TXS0101

The TXS0101 from Texas Instruments is a versatile 1-bit bidirectional voltage-level translator. It is engineered for applications requiring level shifting between different voltage domains, supporting both open-drain and push-pull output types. This device features auto-direction sensing, eliminating the need for a separate direction control signal.

Key electrical characteristics include an input voltage range from 1.2V to 3.6V and an output voltage range from 1.65V to 5.5V. It can achieve data rates up to 50 Mbps, with specific maximums of 24 Mbps for push-pull and 2 Mbps for open-drain configurations. The propagation delay is 165 ns, and it operates with a low supply current of 0.025 mA.

The TXS0101 is designed for robust operation with an operating temperature range of -40°C to 85°C. It includes features like edge rate acceleration, output enable, partial power-down (Ioff), and VCC isolation. ESD protection is provided for both A and B ports, exceeding JESD 22 standards, and latch-up performance is also robust.

Available in multiple package options including USON, SOT-SC70, SOT-23, SOT-5X3, and DSBGA, the TXS0101 is suitable for various space-constrained designs. Its VCC isolation feature ensures that if either VCC input is at GND, both ports enter a high-impedance state. No power-supply sequencing is required, simplifying system design.
