TXS0102DCTRE4

Translators, Level Shifters Overview

The TXS0102DCTRE4 is a 2-bit bidirectional voltage-level translator in an 8-pin SSOP package. It supports A-port voltages of 1.65V to 3.6V and B-port voltages of 2.3V to 5.5V. Maximum data rates are 24Mbps for push-pull and 2Mbps for open-drain configurations. The device operates from -40°C to +85°C with VCCA ≤ VCCB.

Translators, Level Shifters Feature Summary

• Auto-direction sensing eliminates the need for external direction-control signals
• Integrated internal pull-up resistors support open-drain applications without external components
• VCC isolation feature places ports in high-impedance state if either supply is at ground
• No power-supply sequencing required as either rail can ramp first

Translators, Level Shifters Applications

• I2C / SMBus interfaces
• UART connections
• GPIO translation

Translators, Level Shifters Procurement Notes

Verify the DCT suffix indicates the SSOP-8 package type. Confirm the E4 suffix denotes lead-free compliance. Ensure the RE4 designation matches the specific reel packaging requirements for your assembly line.

Translators, Level Shifters Selection Notes

Select this component when translating between mixed-voltage systems requiring bidirectional flow. Ensure VCCA does not exceed VCCB. Verify that the application utilizes push-pull or open-drain drivers compatible with the integrated 10kΩ pull-ups.

Translators, Level Shifters Part Context

This part belongs to the Texas Instruments TXS0102 family of Switch-type voltage translators. It provides two independent channels for level shifting. The DCTRE4 variant specifically combines the SSOP-8 physical form factor with tape-and-reel delivery for automated manufacturing.

Translators, Level Shifters FAQ

Does the TXS0102 require a direction control pin?

No, the device uses auto-direction sensing to determine data flow without a direction-control signal.

What is the function of the OE pin?

Setting the OE input low places all I/Os in a high-impedance state to reduce quiescent current consumption.
