TXB0102DCUTG4

Translators, Level Shifters Overview

Texas Instruments TXB0102DCUTG4 is a dual-channel bidirectional voltage-level translator housed in an 8-pin VSSOP package. It supports a VCCA supply range of 1.2V to 3.6V and a VCCB range of 1.65V to 5.5V, enabling translation between different logic families. The device features automatic direction sensing for seamless data transfer without requiring a direction control pin. It operates within a temperature range of -40°C to +85°C and offers a propagation delay of 7.4ns.

Translators, Level Shifters Feature Summary

• Automatic direction sensing eliminates the need for external direction control pins
• Supports bidirectional data transfer between 1.2V and 5.5V logic domains
• Compatible with CMOS and TTL input logic standards

Translators, Level Shifters Applications

• Connecting low-voltage processors to higher-voltage peripheral interfaces
• Level shifting between I2C or SPI buses operating at different voltages
• Interface bridging in mixed-voltage embedded systems

Translators, Level Shifters Procurement Notes

Verify the DCUTG4 suffix indicates lead-free and RoHS-compliant construction consistent with Texas Instruments standards. Confirm the VSSOP-8 package dimensions match your PCB footprint requirements. Ensure the ordering code matches the specific tape-and-reel or cut-tape availability needed for your assembly process.

Translators, Level Shifters Selection Notes

Select this component when bidirectional level translation is required without dedicated control lines. It is suitable for applications needing fast switching speeds under 7.4ns propagation delay. Consider the wide supply voltage ranges if interfacing diverse logic families. Verify thermal performance meets system requirements within the specified operating temperature range.

Translators, Level Shifters Part Context

The TXB0102 belongs to Texas Instruments' TXB series of voltage-level translators. This family provides compact solutions for interfacing digital components operating at different supply voltages. The DCUTG4 variant specifically denotes the VSSOP-8 surface-mount package with green (lead-free/RoHS) materials.

Translators, Level Shifters Replacement Considerations

TXB0102DCUR serves as a functional equivalent with identical electrical characteristics but may differ in packaging format. TXS0102DCUR is another alternative within the same family, though it exhibits slower propagation delays compared to the TXB0102 series.
