Overview
The SN74AUP1G02DBVT is a low-power single 2-input positive-NOR gate from the Texas Instruments AUP 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 a maximum propagation delay of 4.6 ns at 3.3 V with a 5 pF load, ensuring high-speed performance in portable applications. Static power consumption is limited to 0.9 μA maximum, while dynamic power consumption is characterized by a typical capacitance of 4.3 pF at 3.3 V. Input hysteresis is typically 250 mV at 3.3 V, providing noise immunity.
Feature Summary
- Ultra-small footprint available in packages such as X2SON (DPW) with a 0.64 mm² body size.
- Low static and dynamic power consumption suitable for battery-powered portable applications.
- Ioff circuitry supports live insertion, partial-power-down mode, and back-drive protection.
- Input hysteresis allows slow input transitions and improves switching-noise immunity.
Applications
- ATCA Solutions
- Active Noise Cancellation (ANC)
- Barcode Scanner
- Blood Pressure Monitor
- CPAP Machine
Procurement Notes
Verify the specific package suffix against the datasheet orderable addendum to ensure correct physical dimensions and pinout compatibility. Confirm that the ordering suffix matches the required reel or cut tape quantity specifications. Ensure the component meets RoHS compliance requirements for the target assembly process. Validate thermal resistance parameters if high-density board layouts are utilized.
Selection Notes
Select this component when ultra-low power consumption and minimal board space are critical design constraints. The wide operating voltage range supports mixed-mode signal operations between different logic families. The built-in input hysteresis makes it suitable for environments with noisy signals or slow transition rates. Verify that the application does not require higher drive currents than the standard output capabilities provide.
Part Context
This device belongs to the SN74AUP1Gxx series of single-function gates designed for low-voltage digital logic applications. The AUP family represents Texas Instruments' solution for minimizing power consumption in portable electronics while maintaining signal integrity. It complements other single-gate variants like the NAND (SN74AUP1G00) and NOR (SN74AUP1G02) functions within the same technology node.

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 slow input transitions and provides better switching-noise immunity at the input, which is beneficial in noisy environments.
