Description
The STG4210 is a high-speed CMOS low voltage dual analog SPST (single pole single throw) switch fabricated in silicon gate C2MOS technology. The STG4210 is designed to operate from 1.65 to 4.3 V, making this device ideal for portable applications. The SELn inputs are provided to control the switch operation. The switch Sn is “on” (connected to common ports Dn) when the SELn input is held high and “off” (high impedance state exists between the two ports) when SELn is held low. 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. QFN10L (1.8 x 1.4 mm)
