ADG7421FBCPZ-RL7

ADG7421F is a low voltage, dual single-pole/single-throw (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 the Six pins exceed VDD or VSS by a threshold voltage, VT, the switch automatically turns off and the digital FF (fault flag) pin drops to a logic low to indicate a fault. Input signal levels upto +60V or -60 V relative to ground are blocked, in both the powered and unpowered condition. It is used in application such as analogue input/output modules, process control/distributed control systems, data acquisition, instrumentation, avionics, automatic test equipment, communication systems, relay replacement etc.
