MAXIM 0.7V, Low-Voltage, Quad 2:1 Analog Multiplexers MAX4780, MAX4784 Data Handbook / Owner's Manual
Summary
These quad 2:1 analog multiplexers are designed for efficient signal routing in space-constrained, low-power applications. Operating on a single supply from 1.6V to 4.2V, they feature ultra-low on-resistance and fast switching speeds ideal for battery-powered systems, data acquisition, and audio/video applications. This manual provides comprehensive technical specifications, including electrical characteristics, pin configurations (TSSOP and QFN packages), absolute maximum ratings, and detailed application guidance for engineers designing portable electronics and communications circuits.
