TXB0101DRLT

Translators, Level Shifters Overview

The TXB0101DRLT is a single-channel, bidirectional voltage-level translator manufactured by Texas Instruments. It features auto direction sensing and provides robust electrostatic discharge (ESD) protection rated at ±15 kV. The device utilizes two separate configurable power-supply rails, allowing for universal low-voltage translation between various logic levels including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V. It supports partial-power-down mode operation via the Ioff circuitry, which disables outputs when either supply rail is at ground potential.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for a direction control pin
• High ESD protection rating of ±15 kV on port B
• Supports partial-power-down mode with high-impedance output state
• Configurable dual power-supply rails for flexible voltage translation

Translators, Level Shifters Applications

• Bidirectional level shifting between different voltage domains in embedded systems
• Interface translation for I2C, SMBus, and other open-drain bus protocols
• Connecting microcontrollers operating at lower voltages to peripherals requiring higher logic levels
• Portable electronics requiring low power consumption and partial-power-down capabilities

Translators, Level Shifters Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the ordering suffix corresponds to the required reel quantity and tape-and-reel specifications. Check for any recent product change notifications or lifecycle status updates directly from Texas Instruments before finalizing procurement plans.

Translators, Level Shifters Selection Notes

Select this component when bidirectional data flow is required without external direction control signals. It is suitable for applications needing high ESD immunity and compatibility with multiple voltage standards. Ensure the maximum supply voltage limits for both ports are respected within the system design constraints.

Translators, Level Shifters Part Context

This part belongs to the TXB series of voltage translators from Texas Instruments, designed for general-purpose level shifting. It complements other devices like the TXS and TXU series by offering auto-direction sensing and enhanced ESD protection in a compact surface-mount package.

Translators, Level Shifters Replacement Considerations

Direct substitutes include the TXB0101DBVR and TXB0101DRGR, which share identical electrical characteristics but differ in packaging options.
