Overview
The SN74HC02DBR is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the HC logic series and operates within a supply voltage range of 2 V to 6 V. The device features four independent NOR gates, each with two inputs, housed in a 14-pin TSSOP package. Key electrical characteristics include a low-level output current of 5.2 mA and a high-level output current of -5.2 mA. Propagation delay is specified at 8 ns. The component supports surface-mount installation and functions reliably across an operating temperature range from -40 °C to +125 °C.
Feature Summary
- Provides four independent 2-input NOR logic functions for signal processing
- Operates with a wide supply voltage range supporting 2 V to 6 V systems
- Designed for surface-mount applications using a compact 14-pin TSSOP package
Applications
- Digital logic circuit design requiring NOR functionality
- Signal processing in consumer electronics
- Industrial control systems utilizing HC logic families
Procurement Notes
Verify the specific suffix 'DBR' corresponds to the 14-TSSOP package and reel packaging configuration. Confirm RoHS compliance status and manufacturing origin through official datasheets or authorized distributor documentation before procurement. Ensure thermal management requirements align with the specified operating temperature range during integration.
Selection Notes
Select this component when a quadruple 2-input NOR gate is required in a surface-mount form factor. The HC series offers compatibility with standard CMOS logic levels. Consider the 14-pin TSSOP footprint for PCB layout constraints. Verify that the 2 V to 6 V supply range meets system power requirements and that the propagation delay specifications satisfy timing constraints.
Part Context
This part is part of the SNx4HC02 family of quadruple 2-input positive-NOR gates. It shares functional similarities with other HC series logic devices but is distinct in its specific gate configuration and package type. The DBR suffix indicates the tape and reel packaging format suitable for automated assembly processes.
Replacement Considerations
SN74HC02DR: Same manufacturer, identical logic function, SOIC-14 package. SN74HC02DRE4: Enhanced version with same specifications. Cross-vendor equivalents may require verification of pinout and electrical parameters.
