The AD7503 is identical to the AD7501 except its “enable” logic is inverted. All digital inputs are TTL/DTL and CMOS logic patible. 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.
