SN74S02N

Inverter Gates Overview

The SN74S02N is a quadruple 2-input positive NOR gate manufactured by Texas Instruments. It belongs to the SN74S logic series, utilizing Schottky TTL technology for high-speed operation. The device features four independent NOR gates within a single package. It operates with a supply voltage range of 4.75 V to 5.25 V and supports a low-level output current of 20 mA. The typical propagation delay is specified at 10 ns to 50 ns, with an average drive strength of 8 mA. It is housed in a standard 14-pin PDIP package suitable for through-hole mounting.

Inverter Gates Feature Summary

• Integrates four independent 2-input NOR logic functions
• Utilizes Schottky TTL technology for enhanced switching speed
• Provides robust push-pull output drive capability

Inverter Gates Applications

• High-speed digital logic circuits requiring NOR functionality
• Data processing systems using TTL-compatible interfaces
• Industrial control logic implementations

Inverter Gates Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-14 through-hole package configuration. Confirm RoHS compliance status as detailed in the official datasheet specifications. Ensure the order quantity aligns with tube packaging requirements typically associated with this package style. Validate that the application environment remains within the specified 0°C to +70°C operating temperature range.

Inverter Gates Selection Notes

Select this component when Schottky TTL speed is required over standard LS series performance. The SN74S02N offers faster propagation delays compared to basic TTL variants. Consider the 14-pin DIP form factor for prototyping or legacy board designs. Verify input compatibility with existing TTL signal levels in the system architecture.

Inverter Gates Part Context

This part is a member of the Texas Instruments SN74S family, which introduced Schottky clamping diodes to prevent saturation and improve switching times. The SN74S02N specifically provides NOR logic, contrasting with the NAND-based SN74S00N. It serves as a bridge between older standard TTL and newer advanced logic families in mixed-signal environments.

Inverter Gates Replacement Considerations

SN74S02NS (SOIC-14 surface mount equivalent). SN74LS02N (standard TTL alternative with slower speed). SN74AS02N (Advanced Schottky variant with higher speed).
