I NOTES ON DEVICE HANDLING
Preventing Latch-up
Care must be taken to ensure that maximum voltage ratings are not exceeded when they are used
Latch-up may occur on CMos ICs if voltage higher than Vcc or lower than Vss is applied to input and output pins
other than medium -and high-Withstand voltage pins or if higher than the rating voltage is applied between vcc
pin and vss pin
When latch-up occurs, power supply current increases rapidly and might thermally damage elements
Stable Supply Voltage
Supply voltage should be stabilized
a sudden change in power-supply voltage may cause a malfunction even within the guaranteed operating range
of the Vcc power-supply voltage
For stabilization, in principle, keep the variation in Vcc ripple(p-p value)in a commercial frequency range
(50 Hz /60 Hz not to exceed 10% of the standard vcc value and suppress the voltage variation so that the
transient variation rate does not exceed 0. 1 V/ms during a momentary change such as when the power supply
is switched
Precautions for Use of external clock
Even when an external clock is used, oscillation stabilization wait time is required for power-on reset, wake-up
from sub clock mode or stop mode
Do not use a sample used in program development as mass-produced product
