Overview
The SN74AUC1G04DCKR is a single inverter gate from the Texas Instruments AUC logic family, housed in a 5-pin SC-70 package. It operates within a supply voltage range of 0.8 V to 2.7 V and supports mixed-mode signal operation with 3.6-V I/O tolerance. The device features a maximum propagation delay of 2.2 ns at 1.8 V and offers an output drive capability of ±8 mA at 1.8 V. It includes Ioff circuitry for partial power-down protection and exhibits high ESD resistance exceeding 2000 V via the human-body model.
Feature Summary
- Operates at sub-1-V levels while maintaining 3.6-V I/O tolerance for mixed-mode applications
- Includes Ioff circuitry to disable outputs and prevent back-drive current during partial power-down
- Provides robust electrostatic discharge protection exceeding industry standards
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
Procurement Notes
Verify that the ordering suffix 'DCKR' corresponds to the SC-70 package type and tape-and-reel quantity. Confirm RoHS compliance status and lead finish specifications against the latest Package Option Addendum. Ensure the component meets the required operating temperature range and moisture sensitivity level for your assembly process.
Selection Notes
Select this component when designing low-voltage digital circuits requiring minimal footprint and low power consumption. It is suitable for portable electronics where battery life is critical. Consider the 3.6-V input tolerance if interfacing with higher voltage logic domains without level shifting.
Part Context
This device belongs to the SN74AUC1G04 series of Little Logic inverters. It shares functional characteristics with other members of the AUC family but differs in packaging options such as SOT-23 or DSBGA. The SC-70 variant provides a compact solution for space-constrained printed circuit board layouts.

FAQ
Does the SN74AUC1G04DCKR support partial power-down mode?
Yes, the device includes Ioff circuitry that disables the output to prevent damaging current backflow when the device is powered down.
What is the maximum input voltage tolerance?
The inputs are 3.6-V tolerant, allowing the device to interface with 3.6-V signals even when operating at lower supply voltages.
