PCA9534
8-bit I2C-bus and SMBus low power I/O port with interrupt
[1]
VDD must be lowered to 0.2 V in order to reset part.
[2]
Each I/O must be externally limited to a maximum of 25 mA and the device must be limited to a maximum current of 100 mA.
[3]
The total current sourced by all I/Os must be limited to 85 mA.
10. Dynamic characteristics
[1]
tVD;ACK = time for Acknowledgement signal from SCL LOW to SDA (out) LOW.
[2]
tVD;DAT = minimum time for SDA data output to be valid following SCL LOW.
[3]
Cb = total capacitance of one bus line in pF.
