TXU0304PWR

Overview

The TXU0304PWR is a single-circuit, four-channel unidirectional voltage level translator manufactured by Texas Instruments. It operates with independent supply voltages VCCA and VCCB ranging from 1.08 V to 5.5 V, enabling seamless translation between different logic families. The device supports data rates up to 200 Mbps and features tri-state outputs. It is housed in a 14-TSSOP package and functions reliably within an operating temperature range of -40°C to +125°C.

Feature Summary

• Supports bidirectional voltage translation between low-voltage (1.08V) and high-voltage (5.5V) logic domains
• Provides four independent channels for simultaneous multi-bus interface conversion
• Features tri-state outputs to prevent bus contention during system initialization or power-down states

Applications

• Interfacing low-voltage microcontrollers with 5V peripherals
• Level shifting between I2C, SPI, and UART buses operating at different voltage levels
• Connecting mixed-voltage digital systems in industrial control environments

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging configuration matches your assembly requirements. Confirm that the component meets RoHS3 compliance standards if required by your manufacturing process. Check the latest datasheet revision to ensure all electrical characteristics align with your design specifications before finalizing procurement.

Selection Notes

Select this component when unidirectional translation is sufficient for the application. Ensure both supply rails fall within the 1.08 V to 5.5 V range. Consider the 200 Mbps data rate limit against your system's signal frequency. The 14-TSSOP package requires appropriate PCB footprint design for surface mount assembly.

Part Context

This part belongs to the TXU0304 family of voltage translators designed for flexible interface solutions. It complements other Texas Instruments logic devices by providing robust level shifting capabilities without requiring external components. The device is widely used in embedded systems where multiple voltage domains coexist.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar channel counts and voltage ranges. Verify that any substitute maintains the same unidirectional functionality and package dimensions to ensure mechanical compatibility.
