Note 1:
See EIA specification RS-422 for exact test condition.
Note 2:
This is a current sourced when a high output is shorted to Gnd. Only one output at a
time should be shorted.
Note 3:
Parameter tested Go-no-Go only.
Note 4:
Generator waveform is specified as follows: f=1MHZ, duty cycle=50%, Zo=50 Ohms,
tr=tf<6nS.
Driver input=0V to 3V with measure points equal to 1.5V.
Differential
output Vdiff=Do-Do with measure point equal to 0V.
Note 5:
Generator waveform is specified as follows: f=1MHZ, duty cycle=50%, Zo=50 Ohms,
tr=tf=<6ns.
EN/EN inputs = 0V to 3V with measure points equal to 1.5V on the inputs,
to 1.3V on the outputs for ZL and ZH, and (Vol+0.3V) for LZ, and (Voh-0.3V) for HZ.
