NOTES:
Number of Loaded Outputs
Number of Loaded Outputs
1. Duty Cycle is taken from typical chip measured at 1.4V.
2. IDD data is calculated from IDD = ICORE + nCVf, where ICORE is the Unloaded Current (n = Number of Outputs; C = Capacitance Load per Output (F); V = Voltage Supply(V);
f = Frequency (Hz).
