Overview
The SN74AUC02RGYR is a quadruple 2-input positive-NOR gate from the Texas Instruments AUC logic series. It operates within a supply voltage range of 0.8 V to 2.7 V and features a maximum propagation delay of 2.2 ns at 1.8 V. The device provides ±8-mA output drive capability at 1.8 V and includes Ioff circuitry for partial-power-down mode support. It is housed in a 14-pin VQFN package with dimensions of 3.5 mm by 3.5 mm.
Feature Summary
- Supports mixed-mode signal operation through 3.6-V I/O tolerance while operating at 1.8 V.
- Enables partial-power-down applications via integrated Ioff circuitry that disables outputs to prevent backflow current.
- Provides robust ESD protection exceeding JESD 22 standards for human-body, machine, and charged-device models.
Applications
- Mixed-mode signal processing between different voltage domains
- Partial-power-down system configurations requiring output isolation
- Low-voltage digital logic control circuits
Procurement Notes
Verify the specific ordering suffix matches the required tape and reel packaging configuration. Confirm the moisture sensitivity level rating aligns with your assembly floor timeline. Ensure the RoHS compliance status meets your environmental regulatory requirements before finalizing procurement orders.
Selection Notes
Select this component when designing systems requiring NOR logic functionality at sub-1-V operational voltages. Consider the 14-pin VQFN package constraints for PCB layout density. Evaluate the 3.6-V I/O tolerance if interfacing with higher voltage peripherals in mixed-signal environments.
Part Context
This part belongs to the SN74AUC02 family of quadruple 2-input NOR gates manufactured by Texas Instruments. It is designed specifically for 1.65-V to 1.95-V VCC operation but remains functional across the broader 0.8-V to 2.7-V range. The RGY suffix denotes the 14-pin VQFN package type used for surface-mount applications.
Replacement Considerations
SN74AUC02RGYR.B serves as an alternative marking variant within the same active production line. Verify pinout compatibility and electrical specifications against existing designs before substitution.
