NOTE FOR SUPPLYING POWER
(1) Timing of power supplying to AC pin
Fig. 15 Timing of power supplying to AC pin
PRECAUTION FOR USE
Connect a capacitor (approx. 0.1µF) between pins V
the shortest distance using relatively thick wire to prevent noise and
latcj up.

Notes on noise and latch-up
The internal circuit of M35060-XXXSP is reset when the level of
the auto clear input pin AC is “L”.
This pin is hysteresis input with the pull-up resistor. The timing
about power supplying of AC pin is shown in Figure 15.
