The Analog Devices ADG749BKSZ-REEL7 is a CMOS 2:1 multiplexer and SPDT analog switch in a 6-pin SC-70 package, supplied on tape and reel. It operates from a single 1.8V to 5.5V supply with one input routed to either of two outputs, and draws just 1µA of supply current. On-resistance is recorded as 5Ω, while the product name cites 2.5Ω. Switching times are 7ns turn-on and 3ns turn-off, and the operating range is -40°C to 125°C. Because it is a CMOS switch rather than a logic gate, it passes analog signals in both directions with no defined signal direction.

The ADG749BKSZ-REEL7 is used to route one analog or digital signal between two destinations, or to select one of two sources into a single destination, under logic control. Typical applications include multiplexing sensor channels into a single ADC input, selecting between two clock or reference sources, switching audio and video signal paths, antenna and test-point selection, and gain-range switching in instrumentation front ends. The 1µA supply current and 1.8V minimum supply suit battery-powered and portable designs, while the tiny SC-70 body allows placement right at the signal source to keep parasitic capacitance low. Note that the record lists Lead Free as Contains Lead alongside RoHS Compliant, which are mutually contradictory, and gives power dissipation as both 5µW and 315mW; confirm the ordering option before designing in.
