Unless otherwise stated, all power supplies = 3.3V ± 5%, no load on any output, and ambient temperature range TA = 0°C to 70°C. Parameters denoted with an asterisk ( * ) represent
nominal characterization data and are not currently production tested to any specific limits. Min. and Max. characterization data are ± 3s from typical.
