DESCRIPTION

The STG3699A is a high-speed CMOS low
voltage quad analog S.P.D.T. (Single Pole\Dual

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 (RON<0.5Ω) at

exists between the two ports) when nIN is held
low; the switches nS2 are ON (they are connected
to common Ports Dn) when th e nIN input is held
low and OFF (high impedance state exists
between the two ports) when IN is held high.
Additional key f eatures are fast switch ing 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 is available in the
commercial temperature range (-40 to 125

°C)in
