SCL Low Pulsewidth
SCL High Pulsewidth

Data Hold Time
Setup Time for Repeated Start
Stop Condition Setup Time
Bus Free Time between a STOP
Condition and a START Condition
Pulsewidth of Spike Suppressed
Capacitive load for each bus line
Noise margin at the LOW level for each
connected device (including
hysteresis)
Noise margin at the HIGH level for each
connected device (including
hysteresis)
All timings specifications are referred to VILmin and VIHmax voltage levels defined for the SCL and SDA pins.
The digital interface is reset if the SCL is low more than t
register setting.
A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system.
The device internally provides a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the
undefined region of the falling edge of SCL.
Cb = total capacitance of one bus line in pF. If mixed with Hs-mode devices, faster fall-times according to Table 6 are allowed.
