DESCRIPTION

The STG3685 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 1.4V to

4.3V, making this device ideal for portable

applications.

It offers very low ON-Resistance (<0.5

Ω) at

switches. The switches nS1 are ON (they are

connected to common Ports Dn) when the IN input

is held high and OFF (high impedance state exists

between the two ports) when IN is held low; the

switches nS2 are ON (they are connected to

common Ports Dn) when the IN 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

and

Ultra

Low

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 Flip-chip package with Epoxy

Protection.
