NOTES:
1. C
b
= total capacitance of one bus line in pF.
2. t
VD;ACK
= time for Acknowledgement signal from SCL LOW to SDA (out) LOW.
3. t
VD;DAT
= minimum time for SDA data out to be valid following SCL LOW.
4. t
PV
measured from 0.7V
DD
on SCL to 50% I/O output.
5. Resetting the device while actively communicating on the bus may cause glitches or errant STOP conditions.
6. Upon reset, the full delay will be the sum of t
RESET
and the RC time constant of the SDA bus.
