... D High Speed—t : 170 ns ON DESCRIPTION The DG485 is an analog switch array consisting of eight SPST switches connected to a common output. This device may be used as an 8-channel multiplexer in serial control applications. Any, all or none of the eight switches may be closed at any given time. Combining low on-resistance (r and fast switching (t : 170 ns, typ ...
