Overview

The TXS0104VPWR is a 4-bit bidirectional voltage level translator designed for interfacing between different logic voltage domains without a direction-control signal. It supports bridge operations between VCCA (1.65V to 3.6V) and VCCB (2.3V to 5.5V), making it suitable for mixed-signal CMOS environments. The device features an auto-sensing architecture that automatically detects the direction of data flow for both open-drain and push-pull applications.

Why Choose This Part

The TXS0104VPWR eliminates the need for a direction-control signal, simplifying PCB routing and reducing microcontroller pin usage. It is highly versatile, supporting both push-pull and open-drain output types on a single device. Integrated ESD protection and the lack of power-supply sequencing requirements improve system reliability and ease of design.

Applications

I2C Level Shifting
Translates SDA and SCL lines between 1.8V microcontrollers and 3.3V or 5V peripherals in open-drain configurations.
UART Communication
Enables bidirectional TX/RX serial data exchange between low-voltage application processors and higher voltage legacy modules.
GPIO Interfacing
Provides 4-bit general purpose level translation for status signals and control lines across different power domains.
SPI Bus Translation
Supports data rates up to 24Mbps for shifting SPI clock and data lines between diverse logic families.

Getting Started

To use the TXS0104VPWR, connect the lower voltage rail to VCCA and the higher voltage rail to VCCB. Ensure the OE (Output Enable) pin is tied to VCCA through a pull-up resistor to enable the device during normal operation. For prototyping, look for breakout boards using the 14-pin TSSOP footprint or use a standard TSSOP-to-DIP adapter.
