SN74LS09NSR

Inverter Gates Overview

The SN74LS09NSR is a quad two-input NAND gate integrated circuit manufactured by Texas Instruments. It belongs to the 74LS logic series and features open-collector outputs, allowing for flexible interfacing with various load types. The device operates within a supply voltage range of 4.75V to 5.25V and supports surface-mount installation in a 14-SOIC package. It is designed for commercial temperature environments ranging from 0°C to +70°C.

Inverter Gates Feature Summary

• Contains four independent two-input NAND logic gates
• Features open-collector output configuration for wired-AND capabilities
• Compatible with standard TTL logic families

Inverter Gates Applications

• Digital logic signal processing
• Interface circuits requiring open-collector switching
• General-purpose digital systems

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'NSR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 14-SOIC footprint matches the target PCB design guidelines. Ensure the component meets RoHS3 compliance standards if applicable to the manufacturing environment.

Inverter Gates Selection Notes

Select this component when open-collector NAND functionality is required within a standard 74LS logic family. The open-collector design necessitates external pull-up resistors for proper high-level output states. Consider thermal management requirements for the specified commercial operating temperature range during system integration.

Inverter Gates Part Context

This part is part of the broader 74LS series of low-power Schottky TTL logic devices. The SN74LS09 variant specifically provides open-collector outputs, distinguishing it from standard push-pull NAND gates like the SN74LS00. It serves as a foundational building block for complex digital logic designs requiring specific output drive characteristics.
