40-bit I2C-bus I/O port with RESET, OE and INT
[1]
Minimum SCL clock frequency is limited by the bus time-out feature, which resets the serial bus interface if either SDA or SCL is held
LOW for a minimum of 25 ms. Disable bus time-out feature for DC operation.
[2]
tVD;ACK = time for Acknowledgement signal from SCL LOW to SDA (out) LOW.
[3]
tVD;DAT = minimum time for SDA data out to be valid following SCL LOW.
[4]
A master device must internally provide a hold time of at least 300 ns for the SDA signal (refer to the VIL of the SCL signal) in order to
bridge the undefined region SCL’s falling edge.
[5]
The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at
250 ns. This allows series protection resistors to be connected between the SDA and the SCL pins and the SDA/SCL bus lines without
exceeding the maximum specified tf.
[6]
Cb = total capacitance of one bus line in pF.
[7]
Input filters on the SDA and SCL inputs suppress noise spikes less than 50 ns.
