• Open-collector outputs allow direct interfacing with higher voltage loads

Inverter Gates Applications

• High-voltage signal interfacing
• Logic level translation
• Open-collector bus systems

Inverter Gates Procurement Notes

Verify the component status as End-of-Life or Obsolescence scheduled by the manufacturer. Confirm package type (SOIC-14) and ensure compatibility with existing board layouts. Check for authorized distributors offering genuine Texas Instruments parts to avoid counterfeits.

Inverter Gates Selection Notes

Select this component for designs requiring open-collector NAND gates with high-voltage tolerance. Ensure the application does not require push-pull outputs. Consider alternative LS series parts if the SN74LS26D is unavailable due to obsolescence.

Inverter Gates Part Context

Part of the Texas Instruments SN74LSxx series, known for low-power Schottky bipolar technology. The SN74LS26 specifically addresses high-voltage interface needs compared to standard TTL logic families.

Inverter Gates Replacement Considerations

Check for SN74LS26DE4 as a potential equivalent variant. Verify pinout and electrical specifications against current design requirements before substitution.
