SN74LS02M

Inverter Gates Overview

The SN74LS02M is a Low Power Schottky (LPS) quad 2-input NOR gate manufactured by onsemi. It operates within a supply voltage range of 4.5V to 5.5V and features an operating temperature range of 0°C to 70°C. The device utilizes a 14-pin Small Outline (SOIC) package with a standard 0.300-inch width. Electrical characteristics include a maximum propagation delay of 15ns at 5V with a 50pF load, an input low-level voltage of 0.8V, and an input high-level voltage of 2.0V. Output drive capabilities are specified as 2mA for high state and 20mA for low state.

Inverter Gates Feature Summary

• Integrates four independent 2-input NOR logic gates within a single integrated circuit.
• Utilizes Low Power Schottky technology to achieve high-speed switching performance while maintaining reduced power consumption compared to standard TTL.
• Features buffered outputs designed to provide high noise immunity and stable signal integrity in digital environments.

Inverter Gates Applications

• Implementation of basic Boolean logic functions in digital control systems.
• Construction of complex combinational logic circuits requiring multiple NOR operations.
• Signal processing stages in industrial automation equipment.

Inverter Gates Procurement Notes

Verify the specific suffix 'M' indicates the SOIC package variant when sourcing replacements. Confirm RoHS compliance status as older manufacturing runs may differ from current production standards. Ensure the supplier provides official datasheets matching the SN74LS02M designation to guarantee correct pinout and electrical specifications for design integration.

Inverter Gates Selection Notes

Select this component when a quad NOR gate configuration is required within standard 5V logic families. The Low Power Schottky series offers a balance between speed and power efficiency suitable for general-purpose digital applications. Consider the SOIC package format if surface-mount assembly is preferred over through-hole DIP options for board space optimization.

Inverter Gates Part Context

This component belongs to the widely adopted 74LS logic family, known for its compatibility with standard transistor-transistor logic (TTL) interfaces. The SN74LS02M specifically provides the NOR function, which serves as a universal gate capable of implementing any other logical operation. Its prevalence in legacy and modern designs ensures broad availability of reference materials and compatible peripheral components.

Inverter Gates Replacement Considerations

Compatible substitutes include the DM74LS02N and MC74LS02P. Verify that alternative manufacturers maintain identical pin configurations and electrical tolerances to ensure direct interchangeability without circuit modification.
