16-bit I2C-bus LED driver with programmable blink rates
11. Dynamic characteristics
[1]
tVD;ACK = time for Acknowledgement signal from SCL LOW to SDA (out) LOW.
[2]
tVD;DAT = minimum time for SDA data out to be valid following SCL LOW.
[3]
Cb = total capacitance of one bus line in pF.
[4]
Resetting the device while actively communicating on the bus may cause glitches or errant STOP conditions.
[5]
Upon reset, the full delay will be the sum of trst and the RC time constant of the SDA bus.
