TERMINOLOGY

VDD

Most positive power supply potential.

VSS

Most negative power supply in a dual-supply application. In

single-supply applications, tie this pin to ground.

IDD

Positive supply current.

ISS

Negative supply current.

GND

Ground (0 V) reference.

Source terminal. May be an input or an output.

Drain terminal. May be an input or an output.

RON

Ohmic resistance between Dx and Sx.

ΔRON

On resistance match between any two channels, for example,

RON max − RON min.

RFLAT(ON)

Flatness is defined as the difference between the maximum and

minimum values of on resistance as measured over the specified

analog signal range.

IS(OFF)

Source leakage current with the off switch.

ID(OFF)

Drain leakage current with the off switch.

ID(ON), IS(ON)

Channel leakage current with the on switch.

VD, VS

Analog voltage on the Dx and Sx terminals.

CS(OFF)

Off switch source capacitance. CS (OFF) is measured with

reference to ground.

CD(OFF)

Off switch drain capacitance. CD (OFF) is measured with reference

to ground.

CD(ON), CS(ON)

On switch capacitance. CD (ON), CS (ON) is measured with reference

to ground.

CIN

Digital input capacitance.

tON

Delay time between loading new data to the shift register and

selected switches switching on.

tOFF

Delay time between loading new data to the shift register and

selected switches switching off.

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 because of parasitic capacitance.

Charge Injection

A measure of the glitch impulse transferred from the digital

input to the analog output during switching.

Bandwidth

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

On Response

The frequency response of the on switch.

Insertion Loss

The loss due to the on resistance of the switch. Insertion loss =

20 log10 (VOUT with switch and VOUT without switch).

VINL

Maximum input voltage for Logic 0.

VINH

Minimum input voltage for Logic 1.

IINL, IINH

Input current of the digital input.

IDD

Positive supply current.
