Overview

The TXS0101DRLR is a single-bit, bidirectional voltage-level translator designed for interfacing between different logic voltage domains. It features auto-direction sensing, which eliminates the need for a direction-control signal, and supports both open-drain and push-pull applications.

Why Choose This Part

The device provides seamless integration by requiring no direction-control signal, reducing pin count and firmware complexity. It supports a wide VCCA range of 1.65V to 3.6V and VCCB range of 2.3V to 5.5V, provided VCCA stays below or equal to VCCB. Additionally, it features VCC isolation to ensure outputs are in a high-impedance state if either supply is at ground.

Applications

I2C Level Shifting
Translating SCL and SDA lines between 1.8V controllers and 3.3V or 5V sensors in open-drain mode.
GPIO Voltage Adaptation
Connecting a low-voltage MCU pin to a higher voltage peripheral status LED or control signal.
UART Logic Translation
Level shifting TX or RX lines at data rates up to 24Mbps in push-pull configurations.
One-Wire Interface
Interfacing with Dallas One-Wire devices that require open-drain pull-up logic across different voltage rails.

Getting Started

Ensure that VCCA is connected to the lower voltage supply and VCCB to the higher supply for proper operation. No external pull-up resistors are required for push-pull operation as they are integrated into the IC, though external resistors can be added for open-drain I2C bus requirements. Place decoupling capacitors close to the VCCA and VCCB pins to maintain signal integrity at high speeds.

Also Consider

TXB0101DRLR TITexas Instruments - Best for pure push-pull applications where high drive strength and signal integrity are prioritized over open-drain compatibility.
SN74LVC1T45DRLR TITexas Instruments - Offers higher drive current and supports a wider voltage range but requires a dedicated DIR pin to control signal direction.
