TXU0102QDTTRQ1

Overview

The TXU0102QDTTRQ1 is an automotive-grade, dual-supply, non-inverting fixed-direction voltage-level translator with Schmitt-trigger inputs and three-state outputs. It supports data transmission between ports operating from 1.1 V to 5.5 V. The device features low power consumption of 2.5 µA maximum at 25°C and up to 200 Mbps support for 3.3 V to 5.0 V applications. It operates within a temperature range of –40°C to +125°C and includes VCC isolation and Ioff-float capabilities.

Feature Summary

• Fully configurable dual-rail design allows each port to operate from 1.1 V to 5.5 V
• Schmitt-trigger inputs allow for slow and noisy input signals
• VCC isolation and VCC disconnect (Ioff-float) feature disables all outputs if either supply is disconnected or below 100 mV
• Pinout compatible with TXB family level shifters

Applications

• Eliminate slow or noisy input signals
• Driving indicator LEDs or buzzers
• Debouncing a mechanical switch
• General purpose I/O level shifting
• Push-pull level shifting for UART, SPI, and JTAG

Procurement Notes

Verify the specific package variant (SON-8 DTT) against the datasheet orderable addendum to ensure correct pinout and thermal characteristics. Confirm AEC-Q100 qualification status for automotive reliability requirements. Check for any recent documentation updates or revision history notes that may affect implementation details.

Selection Notes

Select this component when fixed-direction translation is required between two independently powered domains. Ensure the OE pin control logic aligns with the system's power sequencing needs. Consider the high drive strength and Schmitt-trigger inputs for robust signal integrity in noisy environments compared to standard translators.

Part Context

This part belongs to the Texas Instruments TXU0102-Q1 family of automotive voltage-level translators. It is designed for asynchronous communication between data buses, providing reliable level shifting in automotive and industrial applications where dual-supply operation and partial-power-down modes are necessary.

Replacement Considerations

The datasheet indicates pinout compatibility with the TXB family level shifters. Designers should verify electrical specifications and functional differences before substituting TXB series components.
