Delay time measured between the 50% points of the eighth clock falling edge and 90% points of the output
when switching from one address state to another.
t

OFF time measured between the 80% points of both switches when switching from one address state to another.
Charge Injection A measure of the glitch impulse transferred from the digital input to the analog output during switching.
OFF Isolation A measure of unwanted signal coupling through an OFF switch.
Crosstalk A measure of unwanted signal is coupled through from one channel to another as a result of parasitic capacitance.
On Response The Frequency Response of the ON Switch.
Insertion Loss The Loss Due to the On Resistance of the Switch.
