Overview
The SN74HC02NSR is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the SNx4HC02 series and utilizes silicon gate CMOS technology. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a low-level output current of 5.2 mA, a high-level output current of -5.2 mA, and a propagation delay of 8 ns. It supports an operating temperature range from -40°C to +125°C. The component is housed in a TSSOP-14 package.
Feature Summary
- Contains four independent 2-input NOR logic gates
- Utilizes silicon gate CMOS technology for low power consumption
- Provides buffered outputs with high noise immunity
Applications
- General-purpose digital logic circuits
- Signal processing applications requiring NOR logic functions
- Industrial control systems operating within specified temperature ranges
Procurement Notes
Verify the specific suffix 'SR' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the order matches the exact part number to avoid discrepancies in package type or manufacturing lot. Cross-reference the datasheet revision date to confirm compliance with current RoHS standards and material declarations before finalizing procurement.
Selection Notes
Select this component when a quadruple 2-input NOR function is required in a compact surface-mount form factor. The HC series offers a balance of speed and power efficiency suitable for general digital applications. Verify that the system voltage falls within the 2 V to 6 V range and that the load conditions do not exceed the specified output current limits of 5.2 mA.
Part Context
This component is part of the SNx4HC02 family of quadruple 2-input positive-NOR gates produced by Texas Instruments. The family shares common logical functionality but varies in packaging, temperature ratings, and specific electrical characteristics based on the suffix. The SN74HC02NSR specifically denotes the commercial grade version in a TSSOP-14 reel package.
Replacement Considerations
Compatible substitutes include other manufacturers' SN74HC02 variants in TSSOP-14 packages, such as those from ON Semiconductor or NXP, provided they meet the same electrical specifications and pinout compatibility.
