C)
2.2 Operating Range
Note)
*1. If the input voltage exceeds a rated value, malfunctioning results, and in the worst case, the IC may be destroyed.
At power-on time, do not apply an input signal prior to VDD.
*2 Under regular operations it will operate in the high speed mode between the range of 4.5-6.0 V
Before moving on to the normal operations after the power down or power on function, it will operate in low
speed between the 60 ms and operates between 3.5 and 6.0 V.
Ensure that an input signal is not input before the VDD when turning on the power. If the input signal should
come first, then add an electric current limited resistance (1k-ohm) in the series with the input ports.
