Inverter Gates Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC-14 package configuration required for your design. Confirm that the component meets RoHS compliance standards as indicated in the manufacturer's documentation. Ensure compatibility with your system's voltage levels and thermal requirements before finalizing procurement.

Inverter Gates Selection Notes

Select this component when noisy signals require Schmitt-trigger hysteresis for clean switching. It is suitable for applications needing significant power reduction compared to LSTTL logic ICs. Consider its wide operating voltage range and ability to drive multiple LSTTL loads if interfacing with legacy TTL circuits.

Inverter Gates FAQ

What is the function of the Schmitt-trigger inputs?

The Schmitt-trigger inputs provide hysteresis, making the device extremely tolerant to slow or noisy inputs.

How should unused inputs be handled?

Unused inputs must be terminated at VCC or GND to prevent undefined operational states.
