TXU0202QDCURQ1

Overview

The TXU0202QDCURQ1 is an automotive-grade, dual-supply, fixed-direction voltage-level translator featuring Schmitt-trigger inputs and three-state outputs. It supports data rates up to 200 Mbps when operating between 3.3 V and 5.0 V supplies. The device accommodates independent A and B port supply voltages ranging from 1.1 V to 5.5 V. It includes integrated static pull-down resistors on inputs to prevent floating states and offers high drive strength of up to 12 mA at 5 V. The component operates within a temperature range of -40°C to +125°C and is housed in an 8-pin VSSOP package.

Feature Summary

• Dual-rail design allows each port to operate independently from 1.1 V to 5.5 V
• Schmitt-trigger inputs enable reliable translation of slow or noisy signals
• VCC isolation and Ioff-float features support partial-power-down mode operation
• OE control logic utilizes VCC(MIN) circuitry for flexible referencing

Applications

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

Procurement Notes

Verify the specific ordering suffix 'DCUR' corresponds to the 8-pin VSSOP package with tape-and-reel packaging. Confirm that the Q1 designation ensures compliance with AEC-Q100 automotive qualification standards. Check the manufacturer's latest documentation for any updates regarding lead times or availability status before finalizing procurement plans.

Selection Notes

Select this component when fixed-direction translation is required between two distinct voltage domains. Ensure the application benefits from the integrated Schmitt triggers for signal integrity. Verify that the OE pin can be controlled via either VCCA or VCCB logic levels. Consider the low power consumption characteristics if battery-operated systems are involved.

Part Context

This part belongs to the TXU0202-Q1 family of single-bit fixed-direction voltage-level translators. It is designed for asynchronous communication between data buses. The device provides noninverting translation capabilities. It is pinout compatible with the TXB family level shifters, facilitating potential design upgrades or replacements in existing architectures.

Replacement Considerations

The TXU0102 variant is available as another option within the same series supporting common applications.
