Overview
The SN74AUC1G02DCKR is a single 2-input positive-NOR gate from the Texas Instruments AUC logic family, housed in a 5-pin SC-70 (DCK) package. It operates within a supply voltage range of 0.8 V to 2.7 V and supports an input voltage up to 3.6 V. The device features push-pull outputs with a maximum low-level output current of 9 mA at 2.3 V and a maximum high-level output current of -9 mA at 2.3 V. Maximum propagation delay is specified as 2.4 ns at 1.8 V with a 30 pF load. Static power consumption is limited to 10 µA maximum.
Feature Summary
- Implements Boolean NOR function Y = A + B
- Supports partial-power-down mode via Ioff circuitry
- Provides over-voltage tolerant inputs for mixed-mode operation
Applications
- Mixed-mode signal processing circuits
- Partial-power-down system configurations
- Low-voltage digital logic applications
Procurement Notes
Verify that the ordering suffix DCKR corresponds to the SC-70 package type and tape-and-reel carrier configuration. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement. Ensure the component matches the specific pinout and marking requirements for the intended PCB layout.
Selection Notes
Select this component when a single 2-input NOR gate is required in a compact surface-mount form factor. The device is optimized for 1.8-V operation but remains functional across the full 0.8-V to 2.7-V range. Consider the 3.6-V input tolerance if interfacing with higher voltage logic domains without external level shifting.
Part Context
This part belongs to the SN74AUC1Gxx series of sub-1-V Little Logic devices. These components utilize NanoFree technology concepts and are designed for high-speed, low-power applications. The AUC family offers performance improvements over standard CMOS technologies while maintaining compatibility with existing logic standards.

FAQ
What is the Boolean function performed by the SN74AUC1G02?
The device performs the positive-NOR function, where the output Y equals A OR B.
How does the Ioff feature benefit the circuit?
The Ioff circuitry disables the outputs to prevent damaging current backflow through the device when it is powered down, supporting partial-power-down modes.
