The MAX14662 is a serially controlled 8 x SPST switch for general purpose signal switching applications. The number of switches makes the device useful in a wide variety of applications while serial control maximizes flexibility with minimal pins. This part features Beyond-the-Rails^™ capability so that ±5.5V signals can be passed with any single supply between +1.6V and +5.5V.

The serial control is selectable between I²C and SPI. Both modes provide individual control of each independent switch so that any combination of switches can be applied. I²C mode provides two address select pins allowing for addressing up to four devices on a single bus. The SPI mode includes a DOUT pin that can be used to chain multiple devices together with a single select signal.

The MAX14662 is available in a 28-pin (4mm x 4mm) TQFN package and is specified over the -40°C to +85°C extended temperature range. The A_ and B_ pins provide ±15kV Human Body Model (HBM) ESD protection.
