ADG5421FBCPZ-RL7

ADG5421F is a dual SPST, low on resistance switch that features overvoltage protection, power-off protection, and overvoltage detection on the source pins. When no power supplies are present, the switch remains in the off condition, and the switch inputs are high impedance. When powered, if the analogue input signal levels on either of the six pins exceed VDD or VSS by the threshold voltage, VT, both switches turn off together, and the open-drain fault flag (FF) pin pulls to a logic low. Input signal levels upto +60 V or -60 V relative to ground are blocked in both the powered and unpowered condition. The switches turn on with a logic 1 input and conduct equally well in both directions. It is used in application like analogue input and output modules, process control and distributed control systems, data acquisition, instrumentation, avionics, automatic test equipment, communication systems, relay replacement etc.
