IS1 is specified at the 5% drop point of output voltage VO under the Output Voltage parameter conditions. Output is OFF when the output control terminal VC is open. Each input level is equivalent to LS-TTL level. Therefore, the device can be driven directly by LS-TTLs. These products cannot be used in the following applications because the built-in foldback-type overcurrent protection may cause errors during start-up stage.
