Overview
The SN74AUP1G02DCKT is a single 2-input positive-NOR gate from the Texas Instruments AUP logic family. It operates within a supply voltage range of 0.8 V to 3.6 V and supports an operating temperature range of -40°C to +85°C. The device features low static power consumption with a maximum ICC of 0.9 μA and a typical dynamic power dissipation capacitance (Cpd) of 4.3 pF at 3.3 V. Propagation delay (tpd) is specified as 4.6 ns maximum at 3.3 V with a 5 pF load. Input hysteresis provides a typical value of 250 mV at 3.3 V, enhancing noise immunity.
Feature Summary
- Supports live insertion and partial-power-down modes via Ioff circuitry that prevents back-driving current when powered off.
- Features input hysteresis to allow slow input transitions and improve switching-noise immunity.
- Provides 3.6-V I/O tolerance to facilitate mixed-mode signal operation and down-translation.
- Delivers low noise performance by limiting overshoot and undershoot to less than 10% of VCC.
Applications
- Active Noise Cancellation (ANC)
- Embedded PC
- Software Defined Radio (SDR)
- HVAC systems
Procurement Notes
Verify the specific package variant against the orderable addendum in the datasheet, as the DCK suffix corresponds to the SC70 package. Confirm RoHS compliance and lead finish specifications for manufacturing compatibility. Ensure design validation accounts for the recommended operating conditions regarding input transition rates and output loading limits.
Selection Notes
Select this component for applications requiring ultra-low power consumption across a wide voltage range. The AUP family is optimized for battery-powered portable devices where extended life is critical. Consider the built-in hysteresis for environments with noisy signals or slow-rising inputs. Verify that the 3.6-V I/O tolerance meets the requirements for interfacing with higher voltage peripherals.
Part Context
This device belongs to the SN74AUP1Gxx series of single-gate logic ICs manufactured by Texas Instruments. The AUP family is designed to provide industry-leading low-power solutions while maintaining high-speed performance. The SN74AUP1G02 specifically implements the NOR logic function in a compact footprint suitable for space-constrained designs.
Replacement Considerations
Check the orderable addendum for alternative packages such as DBVR or DPWR within the same SN74AUP1G02 family. Cross-reference with other NOR gates in the LVC or AHC families if different voltage tolerances or drive strengths are required.
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.
What is the purpose of the input hysteresis in this gate?
Input hysteresis allows for slower input transitions and provides better switching-noise immunity at the input, ensuring stable operation even with noisy signals.
