TERMINOLOGY

IDD

IDD represents the positive supply current.

ISS

ISS represents the negative supply current.

IN represents the logic control input.

VD (VS)

VD and VS represent the analog voltage on the Dx pins and the

Sx pins, respectively.

RON

RON represents the ohmic resistance between the Dx pins and

the Sx pins.

ΔRON

ΔRON represents the difference between the RON of any two

channels.

RFLAT(ON)

RFLAT(ON) is the flatness that is defined as the difference between

the maximum and minimum value of on resistance measured

over the specified analog signal range.

IS (Off)

IS (Off) represents the source leakage current with the switch off.

ID (Off)

ID (Off) represents the drain leakage current with the switch off.

ID (On), IS (On)

ID (On) and IS (On) represent the channel leakage currents with

the switch on.

VINL

VINL is the maximum input voltage for Logic 0.

VINH

VINH is the minimum input voltage for Logic 1.

IINL, IINH

IINL and IINH represent the low and high input currents of the

digital inputs.

CS (Off)

CS (Off) represents the off switch source capacitance. It is

measured with a reference to ground.

CD (Off)

CD (Off) represents the off switch drain capacitance. It is

measured with reference to ground.

CD (On), CS (On)

CD (On) and CS (On) represent the on switch capacitances,

which are measured with reference to ground.

CIN

CIN is the digital input capacitance.

tTRANSITION

tTRANSITION is the delay time measured between the 50% and 90%

points of the digital inputs and the switch on condition when

switching from one address state to another.

tON (EN)

tON (EN) is the delay time between the 50% and 90% points of

the EN digital input and the switch on condition.

tOFF (EN)

tOFF (EN) is the delay time between the 50% and 90% points of

the EN digital input and the switch off condition.

tOPEN

tOPEN is the off time measured between the 80% points of both

switches when switching from one address state to another

Charge Injection

Charge injection is a measure of the glitch impulse transferred

from the digital input to the analog output during switching.

Off Isolation

Off isolation is a measure of the unwanted signal coupling

through an off switch.

Channel-to-Channel Crosstalk

Crosstalk is a measure of unwanted signal that is coupled

through from one channel to another as a result of parasitic

capacitance.

Insertion Loss

Insertion loss is the loss due to the on resistance of the switch.
