Notes on Circuit Design
When actually design a circuit using these devices, take the following points into consideration and design the circuit so
that none of the maximum rating items are ever exceeded.
• Variations in the supply voltage
• Variations in the electrical characteristics of components such as semiconductor devices, resistors, and capacitors.
• Ambient temperature
• Variations in input and clock signals
• Possible application of abnormal pulses
Also, these devices must be operated within the ranges stipulated in the allowable operating ranges.
If CMOS IC input pins are left open, intermediate potential input voltages may occur leading to incorrect operation due
to through currents or other phenomenon. Applications must handle unused input pins appropriately.
