HANDLING DEVICES
1. Preventing Latchup
Latchup may occur on CMOS ICs if voltage higher than V
CC
or lower than V
SS
is applied to input and output pins
other than medium- and high-voltage pins or if higher than the voltage which shows on “1. Absolute Maximum
Ratings” in “
I
Electrical Characteristics” is applied between V
CC
to V
SS
.
When latchup occurs, power supply current increases rapidly and might thermally damaged elements. When
using, take great care not to exceed the absolute maximum ratings.
2. Treatment of Unused Input Pins
Leaving unused input pins open could cause malfunctions. They should be connected to a pull-up or pull-down
registor.
3. Treatment of N.C. Pins
Be sure to leave (internally connected) N.C. pins open.
4. Power Supply Voltage Fluctuations
Although operating is assured within the rated range of V
CC
power supply voltage, a rapid fluctuation of the
voltage could cause malfunctions, even if it occurs within the rated range. Stabilizing voltage supplied to the IC
is therefore important. As stabilization guidelines, it is recommended to control power so that V
CC
ripple
fluctuations (P-P value) will be less than 10% of the standard V
CC
value at the commercial frequency (50 to 60
Hz) and the transient fluctuation rate will be less than 0.1 V/ms at the time of a momentary fluctuation such as
when power is switched.
5. Precautions when Using an External Clock
When an external clock is used, oscillation stabilization time is required even for power-on reset (optional) and
wake-up from stop mode.
6. Turning on the supply voltage (only for the MB89P175A)
Power on sharply up to the option enabling voltage (2 V) within 13 clock cycles after starting of oscillation.
