PCAL6408A
Low-voltage translating, 8-bit I2C-bus/SMBus I/O expander
a. SDA load configuration
b. P port load configuration
c. RESET timing
CL includes probe and jig capacitance.
All inputs are supplied by generators having the following characteristics: PRR
 10 MHz; Z
o =50 ; tr/tf  30 ns.
The outputs are measured one at a time, with one transition per measurement.
I/Os are configured as inputs.
All parameters and waveforms are not applicable to all devices.
