TITXS0104VBQAR

Overview

The TXS0104VBQAR is a 4-bit bidirectional voltage-level translator designed for interfacing low-voltage microcontrollers with higher-voltage peripherals. It supports both open-drain and push-pull applications, making it suitable for mixed-signal environments without requiring a direction-control signal. The device operates across a wide voltage range, with Port A supporting 1.65V to 3.6V and Port B supporting 2.3V to 5.5V.

Why Choose This Part

The TXS0104V features an auto-direction sensing architecture that eliminates the need for a dedicated DIR pin, simplifying PCB routing and reducing MCU pin count. It is highly versatile by supporting both open-drain and push-pull outputs on the same device. Additionally, the part requires no specific power-supply sequencing, reducing the risk of latch-up during power-on cycles.

Applications

Getting Started

When integrating this WQFN-14 package, ensure the OE (Output Enable) pin is tied to GND through a pull-down resistor to maintain a high-impedance state during power-up. Connect the lower voltage supply to VCCA and the higher voltage supply to VCCB for proper operation. For prototyping, look for breakout boards featuring the TXS0104E or TXS0108E families, as they share the same core translation logic.
