DESCRIPTION

The STG3684 is an high-speed CMOS DUAL

ANALOG S.P.D.T. (Single Pole Dual Throw)

SWITCH or DUAL 2:1 Multiplexer/Demultiplexer

technology. It is designed to operate from 1.65V to

4.3V, making this device ideal for portable

applications.

It offers very low ON-Resistance (<0.5

the switches. The switches nS1 are ON (they are

connected to common Ports Dn) when the nIN

input is held high and OFF (high impedance state

exists between the two ports) when nIN is held

low; the switches nS2 are ON (they are connected

to common Ports Dn) when the nIN input is held

low and OFF (high impedance state exists

between the two ports) when IN is held high.

Additional key features are fast switching speed,

Break Before Make Delay Time and Ultra Low

Power Consumption. All inputs and outputs are

equipped with protection circuits against static

discharge,

giving

them

ESD

immunity

and

transient excess voltage. It’s available in the

commercial

temperature

range

in

the

QFN

package.
