Each input level is equivalent to that for LS-TTL. Therefore, it is possible to be driven directly by an LS-TTL circuit. The SI-3000LSA series employs a foldback-type overcurrent protection circuit. *3: In applications in which a certain current is required for start-up, this circuit may cause a start-up error, and therefore the SI-3000LSA series is not recommended for use in such applications.
