Notes
1.
The rise and fall times specified here refer to the driver device (i.e. not PCF8558) and are part of the general fast
I

C-bus specification. However, when PCF8558 asserts an acknowledge on SDA, the fall time is given by parameter
t
f
. C
b
= capacitive load per bus line.
The device inputs SDA and SCL are filtered and will reject spikes on the bus lines of width <t
SW(max)
.
