Table 14: Serial Interface Timing Specifications
Unless otherwise stated, VDD = 5.0V ± 10%, 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 production tested to any specific limits. MIN and MAX characterization data are ± 3σ from typical.
