O1
and V
O2
on the condition that V
IN
= the condition of protection starting current, I
O
= 10 mA.
*2: Output is OFF when the output control terminal V
C
is open. Each input level is equivalent to LS-TTL. Therefore, the devices can be driven directly by LS-TTLs.
Channels 1 and 2 are turned on or off at the same time.
