[3] a device must internally provide a hold time of at least 300 ns for the sda signal (with respect to the v ih (min) of the scl signal) to bridge the undefined region of the falling edge of scl. [4] c b = total capacitance of one bus line in pf. if mixed with hs-mode devices, faster fall times are allowed. [5] the maximum t f for the sda and scl bus lines is specified at 300 ns. the maximum fall time for the sda output stage t f is specified at 250 ns. this allows series protection re sistors to be connected in between the sda and the scl pins and the sda/scl bus lines without exceeding the maximum specified t f . [6] in fast-mode plus, fall time is specified the same for bot h output stage and bus timing. if se ries resistors are used, desig ners should allow for this when c onsidering bus timing. [7] the maximum t hd;dat could be 3.45 ? s and 0.9 ? s for standard-mode and fast-mode but must be less than the maximum of t vd;dat or t vd;ack by a transition time. this maximum must only be met if the device does not stretch the low period (t low ) of the scl signal. if the clock stretches the scl, the data must be valid by the set-up time before it releases the clock. [8] tsu;dat is the data set-up time that is measured with respec t to the rising edge of scl; applies to data in transmission and the acknowledge. [9] a fast-mode i 2 c-bus device can be used in a standard-mode i 2 c-bus system but the requirement t su;dat = 250 ns must then be met. this will automatically be the case if the device does not stretch the low period of the scl signal. if such a device does stre tch the low period of the scl signal, it must output the next data bit to the sda line t r(max) + t su;dat = 1000 + 250 = 1250 ns (according to the standard-mode i 2 c-bus specification) before the scl line is released. al so the acknowledge timing must meet this set-up time. table 21. dynamic characteristic: i 2 c-bus pins t amb = ? 40 ? c to +105 ? c; 2.2 v ? v dd(reg)(3v3) ? 3.6 v.
