SN74AUC1G07DCKR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G07DCKR is a single buffer/driver with an open-drain output from the AUC logic family. It operates within a supply voltage range of 0.8 V to 2.7 V, specifically optimized for 1.65 V to 1.95 V applications. The device features low power consumption with a maximum ICC of 10 µA and supports partial power-down mode via Ioff circuitry. It provides high ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Propagation delay is maximized at 2.5 ns at 1.8 V under 30 pF load conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Open-drain output configuration enables active-low wired-OR or active-high wired-AND functions when connected to other open-drain outputs.
• Ioff circuitry disables outputs during partial power-down to prevent damaging current backflow through the device.
• High electrostatic discharge protection ratings ensure robustness against human-body, machine, and charged-device models.
• NanoFree package technology utilizes the die as the package to achieve significant reductions in IC footprint size.

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
• Telecom and server AC/DC supply controllers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the SC70-5 package type and tape-and-reel quantity. Confirm RoHS compliance status and lead finish specifications against the latest Package Option Addendum. Ensure the selected variant matches the required operating temperature range and moisture sensitivity level for the intended assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for mixed-mode signal operations requiring 3.6-V I/O tolerance while operating at sub-1-V logic levels. The open-drain architecture is suitable for implementing bus arbitration or level shifting where wired logic connections are necessary. Consider the NanoFree package dimensions if board space constraints are critical compared to standard SOT-23 or TSSOP packages.
