TXU0104PWR

Overview

The TXU0104PWR is a four-channel unidirectional voltage-level translator manufactured by Texas Instruments. It operates with dual power rails ranging from 1.08 V to 5.5 V, supporting data rates up to 200 Mbps. The device features Schmitt-trigger inputs for noise immunity and includes integrated static pull-down resistors. It utilizes a 14-pin TSSOP package and offers a maximum operating temperature of 125°C.

Feature Summary

• Unidirectional translation between two independent voltage domains
• Schmitt-trigger inputs handle slow or noisy signals
• VCC isolation feature disables outputs during partial-power-down
• Integrated pull-down resistors prevent channel floating

Applications

• Eliminating slow or noisy input signals in digital circuits
• Driving indicator LEDs or buzzers from low-voltage logic
• Interfacing different voltage domains in embedded systems

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the 14-pin TSSOP surface-mount package. Confirm the active high OE control logic matches system requirements, as variants like TXUN0104 use active low. Ensure the design supports the specified 1.08 V to 5.5 V rail range for both ports.

Selection Notes

Select this component when unidirectional level shifting is required with Schmitt-trigger noise immunity. It is suitable for applications needing VCC isolation to support partial-power-down modes. Consider pinout compatibility with the TXB family if existing layouts must be maintained without redesigning the footprint.

Part Context

This part belongs to the TXU0104 series of fixed-direction voltage-level translators. It shares pinout compatibility with the TXB family but adds Schmitt-trigger inputs and VCC disconnect features. The PWR suffix specifically denotes the 14-lead thin-shrink small-outline package (TSSOP) used for surface-mount assembly.

Replacement Considerations

TXB0104PWR: Compatible pinout but lacks Schmitt triggers and VCC isolation. TXUN0104PWR: Identical function but uses active-low output enable logic.
