Note 1: All devices are 100% production tested at TA = +25°C and are guaranteed by characterization for TA = TMIN to TMAX, as specified.

Note 2: Output rise and fall times are measured between the 10% and 90% of the VDD power-supply voltage levels. The specification is based

on lab bench characterization and is not tested in production.

Note 3: Timing jitter is the ratio of the peak-to-peak variation of the period to the mean of the period. The specification is based on lab bench

characterization and is not tested in production.
