  • The STG3820 device is a high-speed CMOS low voltage quad analog DPDT (dual pole dual throw) switch or 2:1 multiplexer/demultiplexer switch fabricated in silicon gate C2MOS technology. It is designed to operate from 1.65 V to 4.3 V, making this device ideal for portable applications.

    The SELm-n input is provided to control the 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 switches nS2 and mS2 are ON (connected to common port Dn and Dm respectively) when the SELm-n input is held low and OFF (high impedance state exists between the two ports) when the SELm-n is held high.
    The STG3820 device has an integrated fail safe function to withstand overvoltage condition when the device is powered off. Additional key features are fast switching speed, break-before-make-delay time and ultralow power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.

    Key Features

    • Ultralow power dissipation
      • ICC= 1 μA (max.) at TA= 85 °C
    • Low “ON” resistance
      • RON= 5.4 Ω (TA= 25 °C) at VCC= 4.3 V
      • RON= 6.6 Ω (TA= 25 °C) at VCC= 3.0 V
    • Wide operating voltage range
      • VCC(OPR.) = 1.65 V to 4.3 V
    • 4.3 V tolerant and 1.8 V compatible threshold on digital control input at VCC= 2.3 V to 3.0 V
    • 4 select pins controlling 2 switches each
    • Typical bandwidth (-3 dB) at 800 MHz on all channels
    • USB (2.0) high speed (480 Mbps) signal switching compliant
    • Integrated fail safe function
    • Latch-up performance exceeds 100 mA per JESD 78, Class II
    • ESD performance exceeds JESD22 2000-V human body model (A114-A)
