The ADG526A and ADG527A are CMOS monolithic analog multiplexers with 16 channels and dual 8 channels respectively. On-chip latches facilitate microprocessor interfacing. The ADG526A switches one of 16 inputs to a common output depending on the state of four binary addresses and an enable input. The ADG527A switches one of eight differential inputs to a common differential output depending on the state of three binary addresses and an enable input. Both devices have TTL and 5 V CMOS logic compatible digital inputs.
