4:1 analog mux

18 April 2012 Analogue, Mixed Signal, LSI

The MAX14778 dual 4:1 analog multiplexer (mux) from Maxim supports analog signals up to ±25 V with a single 3,0 to 5,5 V supply. Each mux has separate control inputs to allow independent switching, making the device ideal for multiplexing different communications signals with the same connector pins. Extended ESD protection of ±6 kV (human body model) enables direct interfacing to cables and connectors.

The IC features a low 1,5 Ω (maximum) on-resistance and 3 mΩ (typical) flatness to maximise signal integrity over the entire common-mode voltage range. Each beyond-the-rails mux can carry up to 300 mA of continuous current through it in either direction.
