SN74LS26DR

Inverter Gates Overview

The SN74LS26DR is a quadruple 2-input high-voltage interface positive-NAND gate manufactured by Texas Instruments. It belongs to the 74LS series and features open-collector outputs capable of sinking up to 8mA. The device operates within a standard voltage range and is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package with tape-and-reel packaging for automated assembly.

Inverter Gates Feature Summary

• Provides four independent 2-input NAND logic functions
• Features open-collector outputs suitable for wired-AND configurations
• Designed for high-voltage interface applications

Inverter Gates Applications

• High-voltage logic interfacing
• Wired-OR logic implementation via open-collector outputs
• General-purpose digital logic circuits requiring NAND functionality

Inverter Gates Procurement Notes

Verify the exact suffix against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the SOIC package type matches your PCB footprint requirements. Confirm that the open-collector output characteristics align with your load driving needs before finalizing procurement.

Inverter Gates Selection Notes

Select this component when quad 2-input NAND gates with open-collector outputs are required. It is suitable for designs needing high-voltage tolerance at the output stage. Consider the SOIC package size constraints and the need for external pull-up resistors inherent to open-collector logic families during circuit design.

Inverter Gates Part Context

This part is part of the Texas Instruments 74LS logic family, known for low-power Schottky performance. The 'D' suffix indicates the 14-SOIC package, while 'G4' may denote specific environmental compliance or manufacturing revisions. It serves as a standard discrete logic solution for basic Boolean operations in mixed-signal systems.

Inverter Gates Replacement Considerations

Check for direct equivalents such as the SN74LS26N for PDIP packages or other manufacturers' LS-series NAND gates. Verify that any substitute maintains the same open-collector output structure and high-voltage interface capabilities to ensure functional compatibility.
