SN74LS02NSRG4

Inverter Gates Overview

The SN74LS02NSRG4 is a quad 2-input positive NOR gate from the Texas Instruments 74LS series. It operates within a voltage range of 4.75V to 5.25V and supports a temperature range of 0°C to +70°C. The device features four independent channels, each with two inputs. It utilizes a 14-pin TSSOP package (designated as NS) and has a low-level output voltage of 800mV and a high-level output voltage of 2V.

Inverter Gates Feature Summary

• Contains four independent 2-input positive NOR logic gates
• Compatible with standard 5V TTL logic families
• Provides buffered outputs for improved noise immunity

Inverter Gates Applications

• Digital logic circuit design
• Signal processing systems
• General-purpose computing hardware

Inverter Gates Procurement Notes

Verify that the ordering suffix 'SRG4' corresponds to the specified TSSOP-14 package and lead-free RoHS compliance status. Confirm the manufacturer is Texas Instruments Incorporated. Ensure the component matches the active part status and does not contain discrepancies in the logic family designation or pin configuration compared to official datasheets.

Inverter Gates Selection Notes

Select this component when a quad 2-input NOR function is required in a surface-mount application. It serves as a direct functional replacement for through-hole DIP variants like the SN74LS02N, provided the PCB layout accommodates the smaller TSSOP footprint. Verify that the operating environment remains within the specified commercial temperature limits.

Inverter Gates Part Context

This component belongs to the widely used 74LS (Low-power Schottky) logic family, known for balanced speed and power consumption. The SN74LS02 variant specifically implements NOR logic functions. The 'NS' prefix indicates the TSSOP package type, while 'SRG4' denotes tape-and-reel packaging and environmental compliance.

Inverter Gates Replacement Considerations

The SN74LS02DRE4 is a confirmed equivalent offering identical logical functionality in a SOIC-14 package.
