SN74F02N

Overview

The SN74F02N is a quadruple 2-input positive-NOR gate from the Texas Instruments SN74F logic family. It contains four independent NOR gates in a 14-pin PDIP package. The device operates with a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. Electrical characteristics include a high-level output current of -1 mA and a low-level output current of 20 mA at VCC = 4.5 V. Switching performance under standard test conditions (VCC = 5 V, CL = 50 pF) specifies a typical propagation delay time low-to-high (tPLH) of 4 ns and low-to-high (tPHL) of 2.8 ns.

Feature Summary

• Contains four independent 2-input NOR gates for Boolean logic operations
• Features TTL-compatible inputs and outputs within the F-series logic family
• Provides both inverting and non-inverting signal paths via internal gate configuration

Applications

• Digital logic circuit design requiring NOR functionality
• Data processing systems utilizing F-series logic components
• General-purpose digital applications compatible with 5 V TTL standards

Procurement Notes

Verify that the ordering suffix matches the required package type, as the SN74F02N designation specifically indicates the plastic dual in-line package. Confirm RoHS compliance status and lead finish details through official Texas Instruments documentation or authorized distributors before procurement. Ensure the component meets the specified commercial temperature range requirements for the intended application environment.

Selection Notes

Select this component when a quadruple 2-input NOR gate is required within the SN74F series. Consider the 14-pin PDIP package for through-hole mounting needs. Evaluate switching speed and drive current specifications against system requirements. Verify compatibility with existing TTL logic levels and power supply constraints during the design phase.

Part Context

The SN74F02N belongs to the SN74F logic family, which offers faster switching speeds compared to standard LS-TTL devices while maintaining similar pinouts. This specific part number represents the commercial grade version characterized for operation between 0°C and 70°C. It serves as a standard catalog product for general-purpose digital logic applications.

Replacement Considerations

Compatible substitutes include other SN74F02 variants such as SN74F02DR (SOIC package) or SN74F02NSR (SOP package). Cross-reference with SN54F02 for military-grade temperature ranges if necessary. Verify pinout compatibility and electrical specifications before substitution.

FAQ

What is the maximum low-level output current for the SN74F02N?

The maximum low-level output current (IOL) is 20 mA when the supply voltage is 4.5 V.

Does the SN74F02N support military temperature ranges?

No, the SN74F02N is characterized for operation from 0°C to 70°C. The SN54F02 variant supports the full military temperature range of -55°C to 125°C.
