Overview
The SN74AUP1G02DCKR is a single 2-input positive-NOR gate from the Texas Instruments AUP family, housed in an SC-70 (DCK) package. It operates within a supply voltage range of 0.8 V to 3.6 V and supports a maximum propagation delay of 4.6 ns at 3.3 V with a 30 pF load. The device features low static power consumption of 0.9 μA maximum and dynamic power consumption characterized by a typical capacitance of 4.3 pF at 3.3 V. Input hysteresis provides a typical value of 250 mV at 3.3 V, enhancing noise immunity.
Feature Summary
- Supports partial-power-down mode via Ioff circuitry for live insertion and back-drive protection
- Features input hysteresis to improve switching-noise immunity during slow input transitions
- Provides 3.6-V I/O tolerance to facilitate mixed-mode signal operation
Applications
- Active Noise Cancellation (ANC)
- Embedded PC systems
- Software Defined Radio (SDR)
- HVAC control units
Procurement Notes
Verify that the specific orderable part number matches the required SC-70 package configuration. Confirm compliance with RoHS directives and lead finish specifications such as NIPDAU or SN markings. Ensure the selected variant aligns with the intended operating temperature range and moisture sensitivity level requirements for the manufacturing process.
Selection Notes
Select this component when a NOR logic function is required alongside ultra-low power consumption constraints. The wide operating voltage range allows compatibility with both legacy 3.3-V systems and modern low-voltage microprocessors. The small footprint makes it suitable for space-constrained portable designs requiring high-density integration.
Part Context
This device belongs to the SN74AUP series, which is designed for battery-powered applications requiring minimal quiescent current. The AUP family utilizes advanced CMOS technology to achieve low dynamic power consumption while maintaining excellent signal integrity across the full voltage range.

FAQ
How does the Ioff feature benefit system design?
The Ioff circuitry disables outputs when VCC is 0 V, preventing damaging current backflow through the device and enabling safe live insertion into powered systems.
What is the purpose of the built-in input hysteresis?
Input hysteresis improves switching-noise immunity at the input, allowing the device to handle slower input transition rates without causing erratic output behavior.
