SN74AUP1T17DCKR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUP1T17DCKR is a single Schmitt-trigger buffer gate manufactured by Texas Instruments. It utilizes AUP technology for low power consumption, designed to extend battery life in portable applications. The device accepts 1.8V, 2.5V, or 3.3V LVCMOS input signals and provides a 3.3V CMOS output level referenced to VCC. It operates on a single supply voltage ranging from 2.3V to 3.6V. Key electrical characteristics include an Ioff feature supporting partial power-down mode and optimized current drive capability to minimize signal reflections.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Schmitt-trigger inputs provide noise immunity and improved output signal integrity during slow input transitions.
• Ioff feature supports local power-down conditions when VCC is 0V, allowing safe application of voltages up to 3.6V on inputs and outputs.
• Optimized 4mA current drive capability reduces overshoot, undershoot, and line reflections caused by high-drive outputs.

Buffers, Drivers, Receivers, Transceivers Applications

• Audio interfaces for portable devices
• Single controller systems (analog and digital)
• Solid-state drives (client and enterprise levels)

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the suffix 'DCKR' to ensure the correct SC-70-5 package and tape-and-reel packaging configuration. Confirm that the design requires the specific 2.3V to 3.6V operating range and 3.3V output logic levels defined for this AUP series component before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low-power logic buffering with voltage-level translation capabilities between 1.8V/2.5V inputs and 3.3V outputs. The inclusion of Schmitt-trigger inputs makes it suitable for noisy environments or applications with slow-rising signals where standard buffers might exhibit undefined states.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the SN74AUP1Txx family of low-power, single Schmitt-trigger buffers and translators. It is part of Texas Instruments' broader portfolio of analog and logic solutions designed for mobile and portable electronics. The device shares functional similarities with other AUP series parts but is distinct in its specific voltage translation and buffer configuration.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes within the same family include SN74AUP1T14DCKR (inverter) and SN74AUP1T157DCKR (multiplexer). Cross-manufacturer equivalents should be verified against the SC-70-5 package dimensions and the specific 2.3V-3.6V supply voltage requirements.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature benefit portable designs?

The Ioff feature allows inputs and outputs to be powered down while the device itself is off (VCC=0V), preventing damage when external voltages up to 3.6V are applied. This is critical for maintaining signal integrity in partially powered portable systems.

What is the purpose of the Schmitt-trigger input?

The Schmitt-trigger input suppresses input noise and ensures clean switching even with slowly changing input signals, thereby improving overall output signal integrity compared to standard logic gates.
