TERMINOLOGY

IDD

IDD represents the positive supply current.

ISS

ISS represents the negative supply current.

VD, VS

VD and VS represent the analog voltage on Terminal D and

Terminal S, respectively.

RON

RON is the ohmic resistance between Terminal D and

Terminal S.

ΔRON

ΔRON represents the difference between the RON of any two

channels.

RFLAT (ON)

The difference between the maximum and minimum value of

on resistance as measured over the specified analog signal range

is represented by RFLAT (ON).

IS (Off)

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

ID (Off)

ID (Off) is 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.

CD (Off)

CD (Off) represents the off switch drain capacitance, which is

measured with reference to ground.

CS (Off)

CS (Off) represents the off switch source capacitance, which is

measured with reference to ground.

CD (On), CS (On)

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

are measured with reference to ground.

CIN

CIN represents digital input capacitance.

tON (EN)

tON represents the delay time between the 50% and 90% points

of the digital input and switch on condition. See Figure 33.

tOFF (EN)

tOFF represents the delay time between the 50% and 90% points

of the digital input and switch off condition. See Figure 33.

tTRANSITION

tTRANSITION represents the 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.

tD represents the off time measured between the 80% point of

both switches when switching from one address state to another.

Off Isolation

Off isolation is a measure of unwanted signal coupling through

an off channel.

Charge Injection

Charge injection is a measure of the glitch impulse transferred

from the digital input to the analog output during switching.

Crosstalk

Crosstalk is a measure of unwanted signal that is coupled

through from one channel to another as a result of parasitic

capacitance.

Bandwidth

Bandwidth is the frequency at which the output is attenuated by

3 dB, from its dc level.

Total Harmonic Distortion + Noise (THD + N)

THD + N is the ratio of the harmonic amplitude plus noise of

the signal to the fundamental.

AC Power Supply Rejection Ratio (ACPSRR)

ACPSRR measures the ability of a device to avoid coupling

noise and spurious signals that appear on the supply voltage pin

to the output of the switch. The dc voltage on the device is

modulated by a sine wave of 0.62 V p-p. The ratio of the

amplitude of signal on the output to the amplitude of the

modulation is the ACPSRR. See Figure 23.
