The ADG5412BF has four switches that turn on with Logic 1 inputs. The ADG5413BF has two switches that turn on and two switches that turn off with Logic 1 inputs. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. The digital inputs are patible with 3 V logic inputs over the full operating supply range. When no power supplies are present, the switch remains in the off condition, and the switch inputs are high impedance. Under normal operating conditions, if the analog input signal levels on any switch pin exceed VDD or VSS by a threshold voltage, VT, the switch turns off. Input signal levels up to +55 V and - 55 V relative to ground are blocked, in both the powered and unpowered condition.
