ADI ADG5404FBCPZ-RL7

The ADG5404F is an analog multiplexer composed of four single channels with fault protected inputs. The ADG5404F switches one of the four inputs to a common drain, D, as determined by the 2-bit binary address lines (A0 and A1). An enable digital input, EN, is used to disable all the switches. Each channel 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 compatible with 3V logic inputs over the full operating supply range. When no power supplies are present, the switch remains in the off condition, and the channel inputs are high impedance. Under normal operating conditions, if the analog input signal levels on any Sx pin exceed VDD or VSS by a threshold voltage, VT, the channel turns off and that Sx pin becomes high impedance. If the channel is on, the drain pin reacts according to the drain response (DR) input pin. If the DR pin is left floating or pulled high, the drain remains high impedance and floats. If the DR pin is pulled low, the drain pulls to the exceeded rail. Input signal levels up to +55 V or -55 V relative to ground are blocked, in both the powered and unpowered conditions.
