1. Typical values at 25° C. Maximum values are characterized values and not test limits in production.
2. Production test is performed with 50% duty cycle clock at 1 MHz.
3. Timing limits for clock frequencies less than 1 MHz are scaled with the clock frequency.
4. This parameter is not tested. Values are based on characterization and/or simulation data.
