Sample Application Circuit 3
1/3 Bias (for nornal LCD panels)
LC75874E, 75874W
*2
General-purpose
output ports
Used for functions
such as backlight
control
C ≥ 0.047 µF
From the
controller
Note: *2 When a capacitor except the recommended external capacitance (Cosc = 680 pF) is connected the OSC pin, we recommend that applications
connect the OSC pin with a capacitor in the range 220 to 2200 pF.

C ≥ 0.047 µF
From the
controller
Note: *2 When a capacitor except the recommended external capacitance (Cosc = 680 pF) is connected the OSC pin, we recommend that applications
connect the OSC pin with a capacitor in the range 220 to 2200 pF.
