Overview
The SN74AUC1G14DCKR is a single Schmitt-trigger inverter from the Texas Instruments AUC logic family, housed in a SC-70 (DCK) package. 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 3.6-V I/O tolerance, enabling mixed-mode signal operation. Key electrical parameters include a maximum propagation delay of 2.5 ns at 1.8 V with a 30 pF load, ±8-mA output drive capability at 1.8 V, and a maximum quiescent current of 10 μA.
Feature Summary
- Schmitt-trigger action provides distinct positive-going and negative-going input threshold levels for noise immunity.
- Ioff circuitry supports partial-power-down mode by disabling outputs to prevent damaging backflow currents.
- ESD protection exceeds JESD 22 standards, including 2000-V human-body model and 1000-V charged-device model ratings.
- NanoFree™ package technology utilizes the die as the package for compact footprint integration.
Applications
- AV Receiver
- Embedded PC
- Solid State Drive (SSD): Client and Enterprise
- TV: LCD/Digital and High-Definition (HDTV)
- Wireless Headset, Keyboard, and Mouse
Procurement Notes
Verify the specific ordering suffix 'R' indicates tape and reel packaging configuration. Confirm the DCK package designation corresponds to the SC-70 physical dimensions. Ensure compatibility with the required operating temperature range of -40 °C to +85 °C. Check for RoHS compliance status and lead finish specifications such as NIPDAU in the latest orderable addendum.
Selection Notes
Select this component when sub-1-V operability and low power consumption are critical requirements. The 3.6-V I/O tolerance makes it suitable for interfacing between different voltage domains without level shifting. Consider the NanoFree™ package size constraints against available PCB real estate. Evaluate the propagation delay specifications against system timing budgets under expected load conditions.
Part Context
This device belongs to the SN74AUC1Gxx series of single-gate Little Logic devices. It shares functional similarities with other inverters but distinguishes itself through Schmitt-trigger inputs and ultra-low voltage operation capabilities. The AUC series is designed for high-speed, low-power portable electronics requiring minimal board space.

FAQ
What is the purpose of the Ioff feature?
The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device during partial-power-down applications.
How does the Schmitt-trigger input benefit the circuit?
It provides different input threshold levels for positive-going (VT+) and negative-going (VT–) signals, which helps filter out noise and ensures clean switching transitions.
