Overview
a FEATURES DTL/TTL/CMOS Direct Interface Power Dissipation: 30 ␮W RON: 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.
