TXU0102DCUR

Overview

The TXU0102DCUR is a dual-bit, non-inverting fixed-direction voltage-level translator manufactured by Texas Instruments. It operates with independent supply rails VCCA and VCCB ranging from 1.08 V to 5.5 V. The device supports data rates up to 200 Mbps when translating between 3.3 V and 5.0 V logic levels. It features Schmitt-trigger inputs for noise immunity and provides 3-state outputs controlled by an OE pin. The component is housed in an 8-pin VSSOP package.

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 signal handling
• VCC isolation and VCC disconnect (Ioff-float) feature disables outputs if either supply is below 100 mV or disconnected
• High drive strength capability of up to 12 mA at 5 V

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 VSSOP-8 package variant required for your PCB layout. Confirm that the fixed-direction architecture aligns with your system's data flow requirements, as this differs from bidirectional translators. Ensure the OE pin control logic matches your available supply voltages.

Selection Notes

Select this component when a fixed direction translation is sufficient and high drive strength is needed. It serves as a pinout-compatible replacement for the TXB family but offers superior drive capabilities. Verify that the application does not require automatic direction sensing, which necessitates a different device type.

Part Context

This device belongs to the TXU0x02 series of 2-bit unidirectional voltage-level translators. It shares the same pinout configuration as the TXB0102, facilitating drop-in replacements for designs originally using the TXB family. The series includes variants like the TXU0202 for opposing direction applications.
