STG3682 Low voltage high bandwidth dual SPDT switch Features Ultra low power dissipation: I = 0.2A (Max.) at T = 85C CC A Low ON resistance: R = 4.6 (T = 25C) at V = 4.3V ON A CC R = 5.8 (T = 25C) at V = 3.0V ON A CC QFN10 (1.8mm x 1.4mm) Wide operating voltage range: V (Opr) = 1.65V to 4.3V single supply CC 4.3V tolerant and 1.8V compatible threshold on Description digital control input at V = 2.3V to 3.0V CC Typical bandwidth (-3dB) at 800MHz on all The STG3682 is a high-speed CMOS low voltage channels dual analog S.P.D.T. (Single Pole Dual Throw) Switch or 2:1 Multiplexer /Demultiplexer Switch Latch-up performance exceeds 100mA per 2 fabricated in silicon gate C MOS technology. It is JESD 78, Class II designed to operate from 1.65V to 4.3V, making ESD performance exceeds JESD22 this device ideal for portable applications. 2000-V Human body model (A114-A) The nSEL inputs are provided to control the USB (2.0) High speed (480Mbps) signal switch. The switch S1 is ON (they are connected switching compliant 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 (it is 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. Table 1.
