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 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 channel inputs are high impedance. Under normal operating conditions, if t...
