Overview
The SN74AUP1G00DCKR is a single 2-input positive-NAND gate from Texas Instruments' AUP family, designed for ultra-low power applications. It operates within a supply voltage range of 0.8 V to 3.6 V and features low static-power consumption with a maximum ICC of 0.9 µA. The device supports partial-power-down mode via Ioff circuitry and includes input hysteresis for improved noise immunity. Propagation delay (tpd) ranges from 4.8 ns at 3.3 V to 17.1 ns at 0.8 V under a 5 pF load. It is housed in an SC-70 (DCK) package.
Feature Summary
- Ultra-low static and dynamic power consumption suitable for battery-powered portable applications
- Ioff feature enables live insertion, partial-power-down mode, and back-drive protection
- Input hysteresis provides better switching noise immunity for slow input transitions
- Low noise characteristics with overshoot and undershoot less than 10% of VCC
Applications
- ATCA Solutions
- Active Noise Cancellation (ANC)
- Barcode Scanner
- Blood Pressure Monitor
- CPAP Machine
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and lead time specifications. Confirm that the SC-70 package variant matches the required board layout dimensions. Check for any recent product change notifications regarding assembly sites or material compliance updates before finalizing procurement orders.
Selection Notes
Select this component when minimizing quiescent power is critical for extending battery life in portable devices. The wide operating voltage range allows compatibility with various logic levels, including down-translation from 3.3 V systems. Ensure input signals do not exceed the specified transition rates to maintain signal integrity and avoid excessive power dissipation during switching events.
Part Context
This device belongs to the SN74AUP1Gxx series, representing Texas Instruments' solution for low-power needs in portable electronics. The AUP family utilizes advanced CMOS technology to achieve minimal power consumption across the entire voltage range while maintaining excellent signal integrity and small footprint requirements typical of modern compact electronic designs.

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. This supports live insertion and partial-power-down modes without requiring external isolation components.
What is the purpose of the input hysteresis in this NAND gate?
Input hysteresis allows for slower input transitions and improves switching noise immunity at the input, ensuring stable operation even with noisy or slowly changing signal sources.
