General Description

The MAX14778 dual 4:1 analog multiplexer supports analog signals up to ±25V with a single 3.0 to 5.5V supply. Each multiplexer 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 ±6kV (Human Body Model) enable direct interfacing to cables and connectors.
