C-bus characteristics
Notes
1.
A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the V
IL(min)
of the SCL
signal) in order to bridge the undefined region of the falling edge of SCL.
The maximum f
HD;DAT
has only to be met if the device does not stretch the LOW period t
LOW
of the SCL signal.
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 stretch 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.
C
b
= total capacitance of one bus line in pF.
