Counter Dividers FAQ

Does the SN74LS669N support asynchronous reset?

The datasheet specifies synchronous operation for counting; verify if an asynchronous clear input is present in the specific functional diagram, as some variants may rely on synchronous control signals only.

What is the maximum operating frequency?

The maximum frequency depends on the propagation delay and setup/hold times specified in the electrical characteristics table of the official datasheet.
