Each input level is equivalent to LS-TTL level. Therefore, the device can be driven directly by LS-TTLs. *3: These products cannot be used in the following applications. Because these applications require a certain current at start-up and so the built-in foldback-type overcurrent protection may cause errors during start-up stage.
