Overview
The SN74AHC02RGYRG4 is a quadruple 2-input positive-NOR gate from the Texas Instruments AHC logic family, housed in a 14-pin VQFN package. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range of -40°C to 125°C. The device provides high-level output currents up to -8mA and low-level output currents up to 8mA at 5V. Switching characteristics include typical propagation delays of 5.6ns at 3.3V and 3.6ns at 5V with 15pF load capacitance.
Feature Summary
- Performs Boolean NOR logic functions using four independent 2-input gates
- Operates across a wide supply voltage range from 2V to 5.5V
- Provides robust latch-up performance exceeding 250mA per JESD 17 standards
Applications
- General-purpose digital logic processing
- Signal routing and buffering in embedded systems
- Interface circuits requiring NOR logic functionality
Procurement Notes
Verify the specific ordering suffix RGYR against current TI documentation to confirm the VQFN-14 package type and tape-and-reel carrier format. Confirm RoHS compliance status and moisture sensitivity level ratings prior to assembly planning. Ensure the selected variant matches the required thermal resistance and operating temperature specifications for the target application environment.
Selection Notes
Select this component when a compact surface-mount solution is required for NOR logic operations. The VQFN package offers a small footprint suitable for space-constrained designs. Consider the 2V to 5.5V operating range for compatibility with various system voltages. Evaluate thermal performance requirements against the junction-to-ambient thermal resistance values provided in the datasheet.
Part Context
This part belongs to the SNx4AHC02 series of quadruple 2-input positive-NOR gates manufactured by Texas Instruments. The AHC logic family is designed for high-speed applications with CMOS power consumption. The RGY suffix specifically denotes the 14-pin plastic quad flatpack no-lead (VQFN) package configuration.
Replacement Considerations
SN74AHC02DR: SOIC-14 package variant. SN74AHC02DBR: SSOP-14 package variant. SN74AHC02DGVR: TVSOP-14 package variant. SN74AHC02PWR: TSSOP-14 package variant. SN74AHC02BQAR: WQFN-14 package variant.
