TERMINOLOGY

The series on-channel resistance measured between the S and

D pins.

The channel-to-channel matching of on resistance when

channels are operated under identical conditions.

The variation of on resistance over the specified range produced

by the specified analog input voltage change with a constant

load current.

The sum of leakage currents into or out of an off channel input.

The current loss/gain through an on-channel resistance,

creating a voltage offset across the device.

The current flowing into a digital input when a specified low

level or high level voltage is applied to that input.

The capacitance between an analog input and ground when the

switch channel is off.

The capacitance between the inputs or outputs and ground

when the switch channel is on.

The capacitance between a digital input and ground.

The time required for the switch channel to close. The time is

measured from 50% of the falling edge of the LDSW bit to the

time the output reaches 90% of the final value.

The time required for the switch to open. The time is measured

from 50% of the falling edge of the LDSW bit to the time the

output reaches 10% of the final value.

The time required for the logic value at the GPO pin to settle

after loading a GPO command. The time is measured from 50%

of the falling edge of the LDSW bit to the time the output

reaches 90% of the final value for high and 10% for low.

Total Harmonic Distortion + Noise (THD + N)

The ratio of the harmonic amplitudes plus noise of a signal to

the fundamental.

−3 dB Bandwidth

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

Off Isolation

The measure of unwanted signal coupling through an off switch.

Crosstalk

The measure of unwanted signal that is coupled through from

one channel to another because of parasitic capacitance.

Charge Injection

The measure of the glitch impulse transferred from the digital

input to the analog output during on/off switching.

Differential Gain Error

The measure of how much color saturation shift occurs when

the luminance level changes. Both attenuation and amplifica-

tion can occur; therefore, the largest amplitude change between

any two levels is specified and expressed in %.

Differential Phase Error

The measure of how much hue shift occurs when the luminance

level changes. It can be a negative or positive value and is expressed

in degrees of subcarrier phase.

The minimum input voltage for Logic 1.

The maximum input voltage for Logic 0.

The minimum output voltage for Logic 1.

The maximum output voltage for Logic 0.

Positive supply current.
