SN74AUC1G17DCKR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G17DCKR is a single Schmitt-trigger buffer from the AUC logic family, manufactured by Texas Instruments. It operates within a supply voltage range of 0.8 V to 2.7 V and is optimized for 1.65 V to 1.95 V applications. The device features a non-inverting Boolean function (Y = A) with distinct positive-going and negative-going input threshold levels. It provides an output drive current of ±8 mA at 1.8 V and supports partial power-down mode via Ioff circuitry. The component is housed in a 5-pin SC70 package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Schmitt-trigger action provides different input threshold levels for positive-going and negative-going signals.
• Ioff circuitry disables outputs to prevent damaging current backflow during partial power-down or back-drive conditions.
• Inputs are 3.6-V tolerant, supporting mixed-mode signal operation while powered by lower voltages.

Buffers, Drivers, Receivers, Transceivers Applications

• Portable audio devices such as MP3 players and recorders
• Solid-state drives for client and enterprise systems
• Wireless peripherals including headsets, keyboards, and mice

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DCKR' corresponds to the SC70-5 package and tape-and-reel quantity. Confirm RoHS compliance and lead finish details against the latest Package Option Addendum. Ensure the design accounts for the recommended operating temperature range and thermal resistance metrics for the selected package type.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when sub-1-V operation and high-speed buffering are required. The AUC series offers ultra-high speed performance compared to standard CMOS logic. Verify that the 3.6-V input tolerance meets system interface requirements. Consider the NanoFree packaging technology for space-constrained designs requiring die-level integration.
