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.

CAUTION

¹Do not apply voltages higher than V_DDand V_SSto any other terminal, especially

when V_SS= V_DD= 0 V all other pins should be at 0 V.

²The digital control inputs are diode protected; however, permanent damage may

occur on unconnected units under high energy electrostatic fields. 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.
