TSC80251G2D
11.5 AC Characteristics - SSLC: I
Timings
Notes:
1. At 100 kbit/s. At other bit-rates this value is inversely proportional to the bit-rate of 100 kbit/s.
2. Determined by the external bus-line capacitance and the external bus-line pull-up resistor, this must be < 1 s.
3. Spikes on the SDA and SCL lines with a duration of less than 3·T
