STG6684 High isolation dual SPDT analog switch Features Ultra high off-isolation: -80 dB (typ) at 1 Mhz Ultra low power dissipation: I = 0.2 A (max.) at T = 85 C CC A R on T = 1.30 max (T = 25 C) PEAK n A at V = 4.3 V CC QFN10L (1.8 x 1.4 mm) R on S = 0.55 max (T = 25 C) PEAK n A at V = 4.3 V CC Wide operating voltage range: V (opr) = 1.65 to 4.3 V single supply CC The switch Tn is on (connected to common port 4.3 V tolerant and 1.8 V compatible threshold Dn) when the SELn input is held high and off on digital control input at V = 1.65 to 4.3 V CC (high impedance state exists between the two Typical bandwidth (-3 dB) at 65 MHz on Sn ports) when SELn is held low. channel, 58 MHz on the T channel n Additional key features are fast switching speed, Latch-up performance exceeds 100 mA per break-before-make delay time and ultra low power JESD 78, Class II consumption. All inputs and outputs are equipped ESD performance exceeds JESD22 with protection circuits against static discharge, 2000-V Human body model (A114-A) giving them ESD immunity and transient excess voltage. Description The STG6684 is a high-speed CMOS low voltage dual analog SPDT (single pole dual throw) switch or 2:1 multiplexer/de-multiplexer switch fabricated 2 in silicon gate C MOS technology. The STG6684 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 low and OFF (high impedance state exists between the two ports) when SELn is held high. Table 1.
