... THEORY OF OPERATION The ADG1414 is a set of serially controlled, octal SPST switches. Each of the eight bits of the 8-bit write corresponds to one switch of the device. A Logic 1 in the particular bit position turns the switch on, whereas a Logic 0 turns the switch off. Because each switch is independently controlled by an individual bit, this provides the option of having any, all, or none of the switches turned on ...
