*1. Values in parentheses ( ) are provisional only.

*2. The said values are measured by using the NPC standard jig.

*3. The built-in oscillator stop function does not operate with normal output immediately when OE goes HIGH. Instead, normal output occurs after the

oscillator startup time has elapsed.
