Cautions on power application
To ensure normal operation, always apply power using /CE following the procedure shown below.
1) Input a high level to /CE during and after power application.
2) Hold the high level input to /CE for 200 ns or longer (wait time).
3) Start normal operation after the wait time has elapsed.
