Table 17: Serial Interface Timing Specifications

Unless otherwise stated, all power supplies = 5.0V ± 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 ± 3σ from typical.
