TXS0102VDCUR

Overview

The TXS0102VDCUR is a two-bit bidirectional voltage-level translator manufactured by Texas Instruments. It operates with an A-port supply range of 1.65 V to 3.6 V and a B-port supply range of 2.3 V to 5.5 V, ensuring VCCA does not exceed VCCB. The device supports maximum data rates of 24 Mbps in push-pull configurations and 2 Mbps in open-drain applications. It features integrated 10 kΩ pull-up resistors, eliminating the need for external components. The component utilizes a pass-gate architecture with edge-rate accelerators and is housed in an 8-pin VSSOP package.

Feature Summary

• Auto-direction sensing eliminates the requirement for explicit direction-control signals
• Integrated internal pull-up resistors remove the necessity for external resistor components
• Edge-rate accelerator circuitry enhances signal slew rates and overall data throughput
• Supports partial-power-down mode operation through Ioff functionality

Applications

• I2C and SMBus bus interfaces
• Universal Asynchronous Receiver/Transmitter (UART) connections
• General Purpose Input/Output (GPIO) translation

Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel specifications. Confirm that the intended application maintains the VCCA to VCCB voltage relationship as specified in the datasheet. Ensure compliance with RoHS directives and check for any recent product change notifications affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when interfacing mixed-voltage systems requiring bidirectional translation without control signals. It is optimized for open-drain drivers like I2C but also supports push-pull CMOS logic. Consider the thermal resistance metrics and PCB layout requirements regarding trace length to ensure proper one-shot triggering and signal integrity under varying capacitive loads.

Part Context

This device belongs to the Texas Instruments Switch family of voltage translators. It provides digital switching compatibility between different voltage nodes within electronic systems. The design focuses on establishing seamless communication between lower and higher logic levels while maintaining low quiescent current consumption during high-impedance states.

Replacement Considerations

The TXS0102DCTTG4 serves as an alternative package option within the same functional family.
