STG3820 Low voltage high bandwidth quad DPDT switch Datasheet - production data Description The STG3820 device is a high-speed CMOS low voltage quad analog DPDT (dual pole dual throw) switch or 2:1 multiplexer/demultiplexer switch 2 fabricated in silicon gate C MOS technology. It is designed to operate from 1.65 V to 4.3 V, making this device ideal for portable applications. Flip Chip 30 The SELm-n input is provided to control the (2.0 x 2.4 mm) 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 Features switches nS2 and mS2 are ON (connected to Ultralow power dissipation common port Dn and Dm respectively) when the SELm-n input is held low and OFF (high I = 1 A (max.) at T = 85 C CC A impedance state exists between the two ports) Low ON resistance when the SELm-n is held high. R = 5.4 (T = 25 C) at V = 4.3 V ON A CC The STG3820 device has an integrated fail safe R = 6.6 (T = 25 C) at V = 3.0 V ON A CC function to withstand overvoltage condition when Wide operating voltage range the device is powered off. Additional key features V (OPR.) = 1.65 V to 4.3 V are fast switching speed, break-before-make- CC delay time and ultralow power consumption. All 4.3 V tolerant and 1.8 V compatible threshold inputs and outputs are equipped with protection on digital control input at V = 2.3 V to 3.0 V CC circuits against static discharge, giving them ESD 4 select pins controlling 2 switches each immunity and transient excess voltage.
