Refer to EIA specifications for RS-422 serial protocol for exact test conditions.
Measured per input. All other inputs at V_CC or GND.
This is the current sourced when a high output is shorted to GND. Only one output at a time should be shorted.
Skew is defined as the difference in propagation delays between complementary outputs at the 50% input.
Output disable time is the delay from ENABLE or ENABLE being switched to the output transistors turning off.
The actual disable times are less than indicated due to the delay added by the RC time constant of the load.
C_PD determines the no load dynamic power consumption, P_D = (C_PDV_CC2f) + (I_CCV_CC), and the no load dynamic
power consumption, I_S = (C_PDV_CCf) + I_CC.
