TXU0101DBVR

Overview

The Texas Instruments TXU0101DBVR is a single-channel, fixed-direction voltage-level translator housed in a SOT-23-6 package. It supports dual supply voltages (VCCA and VCCB) ranging from 1.08V to 5.5V. The device features Schmitt-trigger inputs for noise immunity and provides 3-state outputs with high drive strength up to 12mA at 5V. It operates within a temperature range of -40°C to +125°C and includes Ioff protection for partial power-down applications.

Feature Summary

• Schmitt-trigger inputs enable reliable translation of slow or noisy signals
• Integrated static pull-down resistors prevent channel floating when undefined
• Ioff protection ensures zero excessive current during partial power-down states
• OE control logic allows output enable/disable referencing either supply rail

Applications

• Eliminating slow or noisy input signals in digital interfaces
• General purpose I/O level shifting between different voltage domains
• Push-pull level shifting for UART, SPI, and JTAG communication protocols
• Driving indicator LEDs or buzzers with appropriate voltage levels

Procurement Notes

Verify the DBVR suffix corresponds to the SOT-23-6 package and tape-and-reel orientation before integration. Confirm that the specific revision matches the design requirements for operating temperature and electrical characteristics. Ensure compatibility with existing PCB footprints and soldering profiles for surface-mount assembly.

Selection Notes

Select this component when a unidirectional translator is required between two independent power rails. It is suitable for interfacing low-voltage logic with higher-voltage peripherals where signal integrity is critical due to Schmitt-trigger inputs. Consider the 12mA drive capability for direct load driving applications without additional buffering.

Part Context

The TXU0101 belongs to Texas Instruments' family of voltage-level translators designed for asynchronous data bus communication. It offers pinout compatibility with the TXB series, facilitating drop-in replacements in designs requiring flexible voltage translation capabilities across varying supply conditions.

Replacement Considerations

Pin-compatible alternatives include other members of the TXB family level shifters. Verify functional equivalence regarding directionality, supply voltage ranges, and drive strength when substituting.
