Notes on Circuit Design
Take the following operations into account when designing circuits that use these products to assure that none of the
items in the maximum ratings are exceeded.
• Supply voltage variations and fluctuations
• Manufacturing variations in the electrical characteristics of the electrical components, including semiconductor
devices, resistors, and capacitors.
• Ambient temperature
• Variations and fluctuations in the input and clock signals
• Possible application of abnormal pulses
Parameters listed in the allowable operating ranges must never exceed their stipulated ranges.
If input pins to a CMOS IC are left open, through currents may occur in internal circuits to which intermediate potentials
are input and result in incorrect circuit operation. Always verify that any unused pins are set up in appropriate states.
