SN74HC02PWR

Overview

The SN74HC02PWR is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the HC (High-Speed CMOS) 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 and one output. Key electrical characteristics include a low-level output current of 5.2 mA and a high-level output current of -5.2 mA. The typical propagation delay is 18 ns. It supports surface-mount installation in a TSSOP-14 package and functions reliably across an operating temperature range from -40 °C to +125 °C.

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-14 package and reel packaging configuration required for your assembly process. Confirm that the component meets RoHS compliance standards as indicated in official documentation. Ensure the ordering part number matches the exact logic family and pinout specifications needed for your circuit design before finalizing procurement.

Selection Notes

Select this component when a quadruple 2-input NOR function is required in a compact surface-mount format. The HC series offers a balance of speed and power consumption suitable for general-purpose applications. Consider the TSSOP-14 package dimensions for PCB layout constraints. Verify that the 2 V to 6 V operating voltage aligns with your system's power supply rails and that the -40 °C to +125 °C temperature range meets environmental requirements.

Part Context

This component is part of the SN74HC02 family of logic gates produced by Texas Instruments. It serves as a fundamental building block for digital logic circuits, providing reliable NOR functionality. The HC series is widely used in consumer electronics, industrial controls, and computing equipment due to its compatibility with standard CMOS logic levels and broad operating voltage range.

Replacement Considerations

Compatible substitutes include other SN74HC02 variants from Texas Instruments or equivalent parts from manufacturers like NXP and ON Semiconductor. Ensure any replacement maintains the same logic function, package type, and electrical specifications. Verify that alternative sources meet the same quality and reliability standards required for your application.
