FUNCTIONAL BLOCK DIAGRAM
AD7501/AD7503
AD7502
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
1
Do not apply voltages higher than V

and V
SS
to any other terminal, especially
when V
SS
= V
DD
= 0 V all other pins should be at 0 V.
2
The 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.
