O
on the condition that V
IN
= overcurrent protection starting current, I
O
= 10 mA.
*4: Output is OFF when the output control terminal V
C
is open. Each input level is equivalent to LS-TTL level. Therefore, the device can be driven directly by LS-TTLs.
*5: SI-3000KFE cannot be used in the following applications because the built-in foldback-type overcurrent protection may cause errors during start-up stage.
