TERMINOLOGY

Positive supply current.

Negative supply current

Analog voltage on Terminal D and Terminal S.

Ohmic resistance between Terminal D and Terminal S.

On resistance flatness is defined as the difference between the

maximum and minimum value of on resistance as measured

over the specified analog signal range.

On resistance match between any two channels.

Source leakage current with the switch off.

Drain leakage current with the switch off.

Channel leakage current with the switch on.

Maximum input voltage for Logic 0.

Minimum input voltage for Logic 1.

Input current of the digital input.

Off switch source capacitance. Measured with reference to

ground.

Off switch drain capacitance. Measured with reference to

ground.

On switch capacitance. Measured with reference to ground.

Digital input capacitance.

Delay time between the 50% and the 90% points of the digital

input and switch on condition.

Delay time between the 50% and the 90% points of the digital

input and switch off condition.

On or off time measured between the 90% 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 on-off switching.

Off Isolation

A measure of an unwanted signal coupling through an

off switch.

Crosstalk

A measure of an unwanted signal that is coupled through from

one channel to another as a result of parasitic capacitance.

−3 dB Bandwidth

The frequency at which the output is attenuated by 3 dB.

On Response

The frequency response of the on switch.

Insertion Loss

The attenuation between the input and output ports of the

switch when the switch is in the on condition and is due to

the on resistance of the switch.
