The AD7503 is identical to theAD7501 except its “enable” logic is inverted. All digital inputsare TTL/DTL and CMOS logic AD7502 is a monolithic CMOS dual 4-channel analogmultiplexer. Depending on the state of two binary addressinputs and an “enable,” it switches two output buses to twoof eight TablesAD7501A2A1A0EN“ON”5118XXX0NoneAD7503A2A1A0EN“ON”mation furnished by Analog Devices is believed to be accurate andreliable.

Keep unusedunits in conductive foam at all NESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readilyaccumulate on the human body and test equipment and can discharge without detection. Although theAD7501, AD7502, and AD7503 feature proprietary ESD protection circuitry, permanent damagemay occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESDprecautions are recommended to avoid performance degradation or loss of functionality.–2–REV. B
