| a FEATURES DTL/TTL/CMOS Direct Interface Power Dissipation: 30 W R ON: 170 Standard 16-Lead DlPs and 20-Terminal Surface Mount Packages CMOS 4-/8-Channel Analog Multiplexers AD7501/AD7502/AD7503 FUNCTIONAL BLOCK DIAGRAM AD7501/AD7503 GENERAL DESCRIPTION The AD7501 and AD7503 are monolithic CMOS, 8-channel analog multiplexers which switch one of eight inputs to a common output, depending on the state of three binary address lines and an "enable" input. The AD7503 is identical to the AD7501 except its "enable" logic is inverted. All digital inputs are TTL/DTL and CMOS logic compatible. The AD7502 is a monolithic CMOS dual 4-channel analog multiplexer. Depending on the state of two binary address inputs and an "enable," it switches two output buses to two of eight inputs.

Keep unused units in conductive foam at all times. CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD7501, AD7502, and AD7503 feature proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. -2- REV.
