NOTE FOR SUPPLYING POWER
Timing of power supplying to AC pin
The internal circuit of M35046-XXXSP/FP is reset when the level of
the auto clear input pin AC is “L”. This pin in hysteresis input with the
pull-up resistor. The timing about power supplying of AC pin is shown
in Figure 11.

PRECAUTION FOR USE
In order to avoid noise and latch-up, connect a bypass capacitor
( 0.1 F) directly between the V
