Procurement Notes

Verify component authenticity through authorized distributors as the part may be discontinued or superseded by newer series variants. Confirm that the SOT-323-5 package matches the design footprint requirements. Ensure the selected replacement maintains the Schmitt trigger input characteristics and voltage tolerance specifications required for the target application environment.

Selection Notes

Select this component when a single XOR gate with Schmitt trigger inputs is required in a minimal footprint package. It is suitable for applications needing wide voltage operation between 2.0 V and 5.5 V. Consider alternatives if higher fan-out or different pin configurations are necessary. Verify thermal performance and propagation delay limits against the system timing constraints before finalizing the design.
