Overview
The SN74AHC02PWLE is a quadruple 2-input positive NOR gate manufactured by Texas Instruments. It belongs to the AHC logic family and utilizes a TSSOP-14 surface-mount package. The device operates within a supply voltage range of 2 V to 5.5 V, ensuring compatibility with various digital systems. Key electrical characteristics include a propagation delay of 5.1 ns and output drive capabilities of -8 mA for high-level and 8 mA for low-level states. It supports CMOS input types and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides four independent 2-input NOR logic functions in a single integrated circuit
- Features high-speed operation with a propagation delay of 5.1 ns
- Supports wide supply voltage operation from 2 V to 5.5 V
- Delivers strong output drive current of ±8 mA
Applications
- General-purpose digital logic processing
- Signal gating and control circuits
- Embedded system interface logic
Procurement Notes
Verify the specific ordering suffix 'LE' against the manufacturer's latest documentation to confirm lead-free status and RoHS compliance requirements. Ensure the TSSOP-14 package dimensions match your PCB footprint design constraints. Confirm that the selected component meets all environmental specifications required for your final assembly process.
Selection Notes
Select this component when a compact solution for multiple NOR operations is required. The AHC series offers superior speed compared to standard HC logic while maintaining CMOS power efficiency. Verify that the 2 V to 5.5 V operating range aligns with your system's power rails. Consider the TSSOP-14 package size relative to available board space and thermal management needs.
Part Context
This part is a member of the Texas Instruments SN74AHC series, designed for high-speed CMOS applications. It serves as a fundamental building block for complex digital designs requiring NOR functionality. The PWLE suffix indicates a specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes.
Replacement Considerations
Direct pin-compatible alternatives within the same family include the SN74AHC02PWR or SN74AHC02PW. Verify that any substitute maintains the identical TSSOP-14 package and electrical parameters to ensure seamless integration without redesigning the host circuit board.
