TXU0104QPWRQ1

Overview

The TXU0104QPWRQ1 is an automotive-grade, 4-bit fixed-direction voltage-level translator with Schmitt-trigger inputs and 3-state outputs. It supports a fully configurable dual-rail design allowing each port to operate from 1.1 V to 5.5 V. The device achieves up to 200 Mbps data rates for 3.3 V to 5.0 V applications. It features low power consumption of 3 µA maximum at 25°C and 6 µA maximum across the -40°C to +125°C temperature range. The component includes VCC isolation and disconnect (Ioff-float) functionality, ensuring high-impedance states when supplies are disconnected or below 100 mV.

Feature Summary

• Schmitt-trigger inputs effectively eliminate slow or noisy input signals
• Integrated static pull-down resistors prevent channels from floating
• High drive strength capability up to 12 mA at 5 V
• OE control logic allows enable/disable referencing from either A or B port

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 package suffix 'PW' corresponds to the TSSOP-14 form factor required for your PCB layout. Confirm that the Q1 designation meets your project's automotive qualification standards. Ensure supply voltages remain within the 1.1 V to 5.5 V range for both ports during operation.

Selection Notes

Select this component when fixed-direction translation between dissimilar voltage domains is required. It is suitable for applications needing high drive strength and noise immunity via Schmitt triggers. Consider pinout compatibility with the TXB family if drop-in replacement is necessary for existing designs.

Part Context

This part belongs to the Texas Instruments TXU0x04-Q1 family of automotive 4-bit unidirectional voltage-level translators. These devices are designed to interface logic circuits operating at different voltage levels while maintaining signal integrity in harsh automotive environments.

Replacement Considerations

The TXU0104-Q1 is pinout compatible with the TXB0104-Q1 family. Verify that the bidirectional nature of the TXB variant does not conflict with the fixed-direction requirement of the TXU0104QPWRQ1 before substitution.
