[1] Typical output duty cycle of 50 %.
[2] The corresponding frame frequency is f _fr = -^f-₂--^c-₄--^l-^k- .
[3] All timing values are valid within the operating supply voltage and ambient temperature range and are referenced to V_IL and V_IH with an
input voltage swing of V_SS to V_DD.
[4] For I²C-bus timings see Figure 19.
