Table 6: AC Timing Specifications
Unless otherwise stated, all power supplies = 3.465V, no load on any output, and ambient temperature range TA = 25°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 f rom typical.
