Notes
1. All the timing values are valid within the operating supply voltage and ambient temperature range and refer to V
2. The device inputs SDA and SCL are filtered and will reject spikes on the bus lines of widths less than t
3. The rise and fall times specified here refer to the driver device (PCF8575) and are part of the general fast I
