The STG3692 is a high-speed CMOS low voltage quad analog SPDT (single pole dual throw) switch or 2:1 multiplexer /demultiplexer switch developed in silicon gate C2MOS technology. It is designed to operate from 1.65 V to 4.3 V, making this device ideal for portable applications. The nSEL inputs are provided to control the switch. The switch S1 is ON (connected to common ports Dn) when the nSEL input is held high and OFF (high impedance state exists between the two ports) when SEL is held low; the switch S2 is ON (connected to common port D) when the nSEL input is held low and OFF (high impedance state exists between the two ports) when nSEL 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.

STG3696E is a high speed ESD protected dual SPDT (single pole dual throw) switch that combines low distortion audio and accurate USB 2.0 high speed (480 Mbps) data signal switching in the same device. When the audio path is selected, the switch allows the audio signal to swing below ground (up to VCC– 5.0 V). Superior channel-to-channel crosstalk also minimizes interference. Integrated shunt resistors in the device helps to suppress pop noise on the audio path. When VBUSis greater than VBUSTHRES, STG3696E will automatically switch from the audio channel to the USB channel. The device is compatible with the requirements of USB 2.0 and features low on capacitance plus low resistance needed to achieve high performance switching in mobile applications. The device allows the D+/D– pins to withstand an overvoltage condition of 5.5 V in compliant with the USB 2.0 fault protection specification.

The STG3820 device is a high-speed CMOS low voltage quad analog DPDT (dual pole dual throw) switch or 2:1 multiplexer/demultiplexer switch fabricated in silicon gate C2MOS technology. It is designed to operate from 1.65 V to 4.3 V, making this device ideal for portable applications. The SELm-n input is provided to control the switches. The switches nS1 and mS1 are ON (connected to common ports Dn and Dm respectively) when the SELm-n input is held high and OFF (high impedance state exists between the two ports) when the SELm-n is held low. The switches nS2 and mS2 are ON (connected to common port Dn and Dm respectively) when the SELm-n input is held low and OFF (high impedance state exists between the two ports) when the SELm-n is held high. The STG3820 device has an integrated fail safe function to withstand overvoltage condition when the device is powered off. Additional key features are fast switching speed, break-before-make-delay time and ultralow power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.

The STG3856 is a high-speed CMOS low voltage dual analog SP3T (single pole triple throw) switch or dual 3 : 1 multiplexer /demultiplexer switch fabricated in silicon gate C2MOS technology. It is designed to operate from 1.65 V to 4.3 V, making this device ideal for portable applications. The device offers very low ON resistance (< 1.0 Ω) at VCC= 4.3 V. The disabling and enabling of switches are done by setting the 1IN and 2IN control pins. Additional key features are fast switching speed, 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.
