Procurement Notes
Verify that the ordering suffix 'CEX' corresponds to the specific package variant (SOT-23 or SC-70) and tape/reel configuration required for your assembly line. Confirm RoHS compliance status and lead-free green material specifications directly with the manufacturer or authorized distributor before placing orders.
Selection Notes
Select this component when designing low-voltage logic circuits requiring fast switching speeds within the 1.8V to 3.6V range. Ensure the application does not exceed the absolute maximum ratings for input or output voltages. Verify that the chosen package fits the PCB footprint constraints and thermal dissipation requirements.
Part Context
This part belongs to the Pericom SOTiny Gate ST family, now distributed by Diodes Incorporated. It serves as a compact solution for basic logic functions in space-constrained designs. The series emphasizes low power consumption and high speed, making it suitable for modern portable and automotive applications where voltage levels are strictly regulated.
Replacement Considerations
Check datasheets for equivalent 2-input OR gates in the same voltage range. Verify pin compatibility and package dimensions if substituting with other manufacturers' parts. Ensure the replacement meets the required propagation delay and output drive current specifications.
