fastest reset times. The switch can easily handle any amount of

capacitor discharge current subject only to the maximum heat

dissipation of the package and the maximum operating junction

temperature from which repetition can be established.

SWITCHING

Switching time tON and tOFF characteristics are plotted versus

VANALOG and temperature. In all cases, tOFF is designed faster

than tON to ensure a break-before-make interval for SPDT and

DPDT applications. The disable input (DIS) has the same

switching times (tON and tOFF) as the logic inputs (INX).

Switching transients occurring at the source and drain contacts

results from ac coupling of the switching FETs gate-to-source

and gate-to-drain coupling capacitance. The switch turn ON

will cause a negative going spike to occur and the turn OFF will

cause a positive spike to occur. These spikes can be reduced by

additional capacitance loading, lower values of RL, or switching

an additional switch (with its extra contact floating) to the op-

posite state connected to the spike sensitive node.

DISABLE NODE

This TTL compatible node is similar to the logic inputs INX but

has an internal 2

µA current source pull-up. If disable is left un-

connected, it will assume the logic “1” state, then the state of

the switches is controlled only by the logic inputs INX.

POWER SUPPLIES

This product operates with power supply voltages ranging from

±12 to ±18 volts; however, the specifications only guarantee

device parameters with

±15 volt ±5% power supplies. The

power supply sensitive parameters have plots to indicate effects

of supply voltages other than

±15 volts.

Typical Applications

Operation from Single Positive Power Supply

High Off Isolation Selector Switch (Shunt-Series Switch)

4-Channel Sample Hold Amplifier
