STG4160：Low voltage 0.5 Ohm single SPDT switch with break-before-make feature and 15 kV ESD protection

The STG4160 device is a high-speed CMOS low voltage single analog SPDT (single pole dual throw) switch or 2:1 multiplexer/demultiplexer switch fabricated in silicon gate C²MOS technology. It is designed to operate from 1.65 to 4.8 V, making this device ideal for portable applications. It offers low on-resistance (0.40 Ω typ.) at V_CC= 4.3 V. The SEL inputs are provided to control the switches.

The switch S1 is ON (connected to the common port D) when the SEL input is held high and OFF (high impedance state exists between the two ports) when the SEL is held low. The switch S2 is ON (connected to the common port D) when the SEL input is held low and OFF (high impedance state exist between the two ports) when the SEL is held high.

Additional key features are fast switching speed, break-before-make delay time and ultra power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.
