Overview
The TXS0101DCKR is a 1-bit bidirectional voltage-level translator produced by Texas Instruments. This device is designed for open-drain and push-pull applications and is packaged in a SOT-SC70 (DCK) package with 6 pins. It allows for low-voltage bidirectional translation between various voltage nodes such as 1.8V, 2.5V, 3.3V, and 5V. The device features two separate configurable power-supply rails, VCCA and VCCB, which can operate within the ranges of 1.65V to 3.6V and 2.3V to 5.5V, respectively. This flexibility makes it suitable for a wide range of applications requiring voltage level translation.

Key Features
- Latch-up performance exceeds 100mA per JESD 78, class II.
- ESD protection exceeds JESD 22 standards.
- No direction-control signal needed.
- VCC isolation feature – if either VCC input is at GND, both ports are in the high-impedance state.
- No power-supply sequencing required – either VCCA or VCCB can be ramped first.
- Supports partial-power-down mode operation.
- Available in the Texas Instruments NanoFree™ package.
- Output-enable (OE) input to place all outputs in a high-impedance state when set to low.
Applications
The TXS0101DCKR is versatile and can be used in various applications requiring voltage level translation, such as:
- Interface between different voltage domains in mixed-voltage systems.
- Communication between devices operating at different voltage levels.
- Level shifting in embedded systems, industrial control systems, and consumer electronics.
- Applications where ESD protection and latch-up immunity are critical.
