Notes
Pin 8 and pin 7 (DET) are connected through
a capacitor.
9
IF buffer
0
(Also used for control SW)
The IF buffer output is turned on when the
voltage applied to the pin is the
recommended 1.5V or higher.

SD
1.6
This is an active-low output.
This is an open-collector output and can
directly drive an LED. (ICmax = 20mA)
