Common Test/Operating Parameters for Analog Switches  

        

Test Parameter

Unit

Typical Description

Absolute Max. Supply Voltage Range (V+ to V-)

V

This is the maximum voltage that may be applied across V+ and V- of the analog switch.

Example of an Actual Spec: 44 V

Absolute Max. V+ to GND

V

This is the maximum voltage that may be applied across V+ and GND of the analog switch.

Example of an Actual Spec: 25 V

Absolute Max. V- to GND

V

This is the maximum voltage that may be applied across V- and GND of the analog switch.

Example of an Actual Spec: -25 V

Absolute Max. Input Voltage

V

This is the maximum input voltage that may be applied at either the source (S) or drain (D) terminal of the analog switch.

Example of an Actual Spec: V- to V+

+/-Supply Current, +Icc, -Icc

mA

This is the maximum amount of current consumed by the analog switch at its negative supply pin (-Icc) or positive supply pin (+Icc) when it is the 'off' state with all its source and drain pins floating.

Example of an Actual Spec: 2 mA

Continuous Current at S,D

mA

This is the maximum amount of current that can continuously flow through the S and D terminals of the analog switch.

Example of an Actual Spec: 30 mA

'On' Resistance

This is the maximum resistance across the source and drain terminals of the switch when it is in the 'on' or conducting state.

Example of an Actual Spec: 90 Ω when VD = +/-10V and IS = +/- 1 mA with the switch enabled

Source Leakage Current, 'Off'

nA

This is the maximum leakage current at the source when the switch is in the 'off' or non-conducting state.

Example of an Actual Spec: 1 nA when VD = +/-14V and VS = -/+ 14 V with the switch disabled

Drain Leakage Current, 'Off'

nA

This is the maximum leakage current at the drain when the switch is in the 'off' or non-conducting state.

Example of an Actual Spec: 1 nA when VD = +/-14V and VS = -/+ 14 V with the switch disabled

Logic Input High Voltage, VIH (Logic "1")

V

This is the minimum voltage that the digital input pins of the analog switch are guaranteed to recognize as a Logic "1". These digital input pins determine whether the switch is 'on' or 'off'.

Example of an Actual Spec: 2.4 V min.

Logic Input Low Voltage, VIL (Logic "0")

V

This is the maximum voltage that the digital input pins of the analog switch are guaranteed to recognize as a Logic "0". These digital input pins determine whether the switch is 'on' or 'off'.

Example of an Actual Spec: 0.8 V min.

Logic Input Current High, IIH (Logic "1")

A

This is the maximum current that flows through a digital input pin of the analog switch when this input pin is at logic '1'. Example of an Actual Spec: 1A when Vin = 15 V at the pin under test and Vin = 0.8 V for all other digital input pins

Logic Input Current Low, IIL (Logic "0")

A

This is the maximum current that flows through a digital input pin of the analog switch when this input pin is at logic '0'. Example of an Actual Spec: 1A when Vin = 0.8 V at the pin under test and Vin = 2.4 V for all other digital input pins

Turn 'ON' Time

nsec

This is the maximum amount of time needed for the analog switch to be in the 'ON' or conducting state after its digital input pin turns it on.

Example of an Actual Spec: 600 nsec max.

Turn 'OFF' Time

nsec

This is the maximum amount of time needed for the analog switch to be in the 'OFF' or non-conducting state after its digital input pin turns it off.

Example of an Actual Spec: 500 nsec max.
