0.2 (B-point) and 0.8 (C-point). The A-point in the figure
shows the I/O characteristics when the “input voltage V

/sup-
ply voltage V

” is 0.7. And, when V
3
/V
9
is from 0.05V to
about 0.2V (B-point), the duty is controlled to 0%, and when
V
3
/V
9
is from 0.8V (C-point) to t.0V, the duty is controlled to
100%.
The standby Pin8 can forcibly turn off the output transistors
by applying a voltage of about 1.1V or more to this pin.
When it is not necessary to forcibly turn off the output tran-
sistors, Leave the standby Pin8 open.
