C-BUS CHARACTERISTICS
Notes
1.
A device must internally provide a hold time of at least 300 ns for the SDA signal (referenced to the V
IHmin
of the
SCL signal) in order to bridge the undefined region of the falling edge of SCL.
The maximum t
HD;DAT
has only to be met if the device does not stretch the LOW period of the SCL signal (t
LOW(SCL)
).
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 t
LOW(SCL)
. If such a device does
stretch t
LOW(SCL)
, 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.
