Output is ON even when 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.
These products cannot be used in the following applications because the built-in foldback-type overcurrent protection may cause errors during start-up stage.
(1) Constant current load (2) Positive and negative power supply (3) Series-connected power supply (4) V
