t
Delay time between the 50% and 90% points of the digital
inputs and the switch on condition when switching from one
address state to another.
t
Off time measured between the 80% point of both switches
when switching from one address state to another.
V
Maximum input voltage for Logic 0.
V
Minimum input voltage for Logic 1.
I
Input current of the digital input.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another as a result of parasitic capacitance.
Off Isolation
A measure of unwanted signal coupling through an off channel.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during switching.
I
Positive supply current.
I
Negative supply current.
