8. Delay function (S-13D1 Series C / F type)
C / F type in the S-13D1 Series has a built-in delay function that sets the difference of rising time between
channels. If the ON / OFF1 pin and the ON / OFF2 pin are set to ON simultaneously, VOUT2 pin voltage rises after
the delay time (tDELAY = 100 μs typ.).

8. 1 In case ON / OFF2 pin is set to ON later
The VOUT1 pin voltage rises simultaneously when the ON / OFF1 pin is set to ON. After the ON / OFF2 pin is
set to ON, VOUT2 pin voltage rises in 100 μs typ.

8. 2 In case ON / OFF2 pin is set to ON previously
VOUT2 pin voltage does no rise even if the ON / OFF2 pin is set to ON. VOUT1 pin voltage rises if the ON /
OFF1 pin is set to ON. After VOUT1 pin voltage rises, VOUT2 pin voltage rises in 100 μs typ.

Caution Note that the current consumption of less than 10 μA flows during the time period from when
the ON / OFF2 pin is set to ON until the ON / OFF1 pin is set to ON.
