TXU0101DRYR

Overview

The TXU0101DRYR is a single-channel, non-inverting fixed-direction voltage-level translator manufactured by Texas Instruments. It operates with dual supply voltages (VCCA and VCCB) ranging from 1.08V to 5.5V. The device supports data rates up to 200Mbps when operating between 3.3V and 5.0V levels. Key electrical characteristics include a maximum propagation delay of 8ns, a typical quiescent current of 2.5µA at 25°C, and Schmitt-trigger inputs for noise immunity. It features 3-state outputs and an OE pin that can be referenced to either supply rail. The component is housed in a 6-pin SON package (DRY) measuring 1.45mm x 1mm and is rated for operation from -40°C to +125°C.

Feature Summary

• Schmitt-trigger inputs provide noise filtering for slow or noisy signals
• Integrated static pull-down resistors prevent channel floating
• Ioff protection enables partial-power-down mode without excessive current draw
• OE control logic allows enable/disable referencing from either VCCA or VCCB

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 DRY suffix corresponds to the 6-pin SON package configuration. Confirm RoHS compliance status through official documentation. Ensure the ordering part number matches the required tape-and-reel or cut-tape packaging format. Cross-reference the manufacturer's latest datasheet revision for any updates to thermal or electrical specifications before finalizing procurement.

Selection Notes

Select this component for applications requiring unidirectional translation between two independently powered logic domains. It is suitable where low power consumption and high noise immunity via Schmitt triggers are priorities. Verify that the signal direction aligns with the fixed A-to-B transmission capability. Ensure the OE pin requirements match the system's control logic availability on either supply rail.

Part Context

This device belongs to the TXU0101 series of voltage translators. It shares functional similarities with the TXB family regarding pinout compatibility but offers distinct internal architecture optimized for fixed-direction translation. The DRY package variant provides a compact footprint suitable for space-constrained designs compared to larger SOT-23 or SC70 options.

Replacement Considerations

Pinout-compatible alternatives within the same family include other TXB series level shifters. Verify functional equivalence regarding directionality and supply voltage ranges before substitution.
