Overview

The TXU0101DCKR is a single-channel, fixed-direction voltage level translator designed for high-speed data communication up to 200Mbps. It features a dual-rail design allowing for independent configuration of input and output voltage levels from 1.1V to 5.5V, making it highly versatile for interfacing modern low-voltage MCUs with legacy peripherals.

Why Choose This Part

This device includes Schmitt-trigger inputs for improved noise immunity and integrated static pull-down resistors to ensure defined logic states during power-up. It also features Vcc isolation and a disconnect feature that ensures outputs are high-impedance if either power supply is at 0V, preventing backflow current.

Applications

High-Speed SPI Clock Translation
Translating high-frequency clock signals between processors and peripherals operating at different voltage rails.
UART Logic Level Shifting
Providing unidirectional level translation for transmit (TX) or receive (RX) lines in serial communication links.
JTAG Signal Buffering
Interfacing debugging and programming headers to target hardware with mismatched logic levels.
GPIO Voltage Adaptation
Driving 5V logic inputs from a 1.2V or 1.8V microcontroller output while maintaining signal integrity.

Getting Started

When designing with the TXU0101DCKR, ensure that VCCA and VCCB are decoupled with 0.1uF capacitors placed close to the device pins. Since this is a unidirectional translator, the signal flow direction is fixed from the A-port to the B-port (or vice versa depending on the internal architecture), so verify pin mapping against your schematic.

Also Consider

SN74LVC1T45DCKR TITexas Instruments - Offers bidirectional level translation for applications where the signal direction may need to change.
TXB0101DCKR TITexas Instruments - Features auto-direction sensing, eliminating the need for a direction control pin in bidirectional applications.
