Most Positive Power Supply Potential

Most Negative Power Supply in a Dual Supply Application. In single supply applications, this should be tied to

ground close to the device.

Positive Supply Current

Negative Supply Current

GND

Ground (0 V) Reference

S

Source Terminal. May be an input or output

D

Drain Terminal. May be an input or output

IN

Logic Control Input

Analog Voltage on Terminals D, S

Ohmic Resistance between D and S

Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured

over the specified analog signal range.

Source 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.

“ON” Switch Capacitance. Measured with reference to ground.

Digital Input Capacitance

Delay time measured between the 50% and 90% points of the digital inputs and the switch “ON” condition.

Delay time measured between the 50% and 90% points of the digital input and the switch “OFF” condition.

EN)

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

EN digital input and the switch “ON” condition.

EN)

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

EN digital input and the switch “OFF” condition.

“OFF” time measured between the 80% points of both switches when switching from one address state to another.

Charge

A measure of the glitch impulse transferred Injection 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 that 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.
