TXU0304DTRR

Overview

The TXU0304DTRR is a 4-bit fixed-direction voltage-level translator with Schmitt-trigger inputs and 3-state outputs, manufactured by Texas Instruments. It supports data rates up to 200 Mbps for 3.3 V to 5.0 V translations. The device operates with dual supply voltages (VCCA and VCCB) ranging from 1.08 V to 5.5 V. It features an OE pin referenced to either supply, Ioff-float support for partial-power-down modes, and integrated static pull-down resistors. The DTR variant utilizes a 12-pin X2SON package.

Feature Summary

• Schmitt-trigger inputs filter slow or noisy signals
• Ioff-float feature enables safe partial-power-down operation
• OE control logic allows referencing to either VCCA or VCCB
• Integrated static pull-downs prevent channel floating

Applications

• Eliminating slow or noisy input signals
• Driving indicator LEDs or buzzers
• Debouncing mechanical switches
• General purpose I/O level shifting
• Push-pull level shifting for UART, SPI, and JTAG interfaces

Procurement Notes

Verify the specific ordering suffix 'DTR' corresponds to the 12-pin X2SON package configuration required for your design. Confirm that the manufacturer's datasheet specifications align with your system's voltage and thermal requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed unidirectional translation path is sufficient for the application. The inclusion of Schmitt triggers makes it suitable for environments with signal integrity challenges. Ensure the OE pin logic levels are compatible with the chosen reference supply voltage.

Part Context

This part belongs to the TXU0x04 family of 4-bit noninverting voltage translators. It shares pinout compatibility with the TXB family, facilitating drop-in replacements in existing designs while offering enhanced drive strength and configurable control logic capabilities.
