SN74HC02DE4

Overview

The SN74HC02DE4 is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the HC (High-speed CMOS) logic family and operates within a supply voltage range of 2 V to 6 V. The device features six circuits in a single package, utilizing standard CMOS input and output types. It is housed in a 14-pin SOIC surface-mount package with an operating temperature range from -40 °C to +85 °C. Key electrical characteristics include a maximum propagation delay of 20 ns, a low-level output current of 4 mA, and a high-level output current of -4 mA.

Feature Summary

• Implements four independent 2-input NOR logic functions within a single integrated circuit.
• Utilizes High-speed CMOS technology for compatibility with standard digital systems.
• Provides robust noise immunity and stable operation across a wide voltage range.

Applications

• General-purpose digital logic signal processing
• Boolean logic implementation in control circuits
• Signal inversion and combination in embedded systems

Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's latest documentation to confirm compliance status and material composition details. Confirm that the SOIC-14 package dimensions match the design footprint requirements. Ensure the operating temperature range meets the environmental specifications of the target application before finalizing procurement.

Selection Notes

Select this component when a quadruple 2-input NOR function is required in a space-constrained surface-mount design. The HC series offers a balance of speed and power consumption suitable for general digital applications. Verify that the 2 V to 6 V supply voltage range aligns with the system power rails and that the 4 mA drive capability is sufficient for the connected loads.

Part Context

This part is a variant of the SN74HC02 series, distinguished by the 'D' indicating the SOIC package and 'E4' denoting environmental compliance attributes. It serves as a fundamental building block in digital electronics, providing reliable NOR logic operations. The device is part of Texas Instruments' extensive portfolio of standard logic ICs designed for broad industrial and commercial use.

Replacement Considerations

Compatible substitutes include CD74HC02M96 and SN74HC02PWR. Verify pinout compatibility and electrical parameter equivalence before substitution.
