The Fairchild FPA700 is a very early phototransisor array, which was first produced in the late 1960s. Intended for use in paper-tape reading machines, the FPA 700 is constructed out of nine NPN phototransistor dies packaged in a crude plastic encapsulation. Each phototransistor is protected by a layer of transparent resin and is wired to a dedicated pair of gold leads. The FPA 700 is rated for a maximum of 20 volts and 25ma of current per phototransistor cell. The example shown here has a date code of 1969.
