Notes:
1. V
IN(DC)
specifies the allowable DC excursion of each input of a differential pair.
2. V
ID(DC)
specifies the input differential voltage, i.e. the absolute value of the difference between the two voltages of a differential
pair.
3. V
ID(AC)
specifies the input differential voltage required for switching.
4. The typical value of V
IX(AC)
is expected to be 0.5 V
DD
and is expected to track variations in V
DD
.
