General Description
The MAX14777 quad SPST switch supports analog
signals above and below the rails with a single 3.0V to 5.5V supply. The device features a selectable -15V/+35V or -15V/+15V analog signal range for all switches. Each switch has a separate control input to allow independent switching, making the device an alternative to opto-relays in applications that do not need galvanic isolation.
