This electronic part is conveniently packaged in 16-TSSOP (0.173, 4.40mm Width), making it easy to ship abroad. This high-reliability packaging method uses advanced packaging methods Tape & Reel (TR). A switch device like this is mounted in Surface Mount. 1:1 is the ratio of multiplexer to demultiplexer circuits. An extended operating temperature of -40°C~85°C TA degrees Celsius. An injection of 16 pins is performed into the body of the electrical component. Unlike digital switches, these are based on SPST - NC switching circuits. 4 circuits are used in this analogue multiplexer. Try searching for ISL43143 variants of the analog switch ic.
