Low-voltage translating, 8-bit I2C-bus/SMBus I/O expander
a. P port load configuration
b. Write mode (R/W =0)
c. Read mode (R/W =1)
CL includes probe and jig capacitance.
tv(Q) is measured from 0.7  VDD(I2C-bus) on SCL to 50 % I/O (Pn) output.
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.
All parameters and waveforms are not applicable to all devices.
