Description

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 independentswitch 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°Cextended temperature range. The A_ and B_ pins provide ±15kV Human Body Model (HBM) ESD protection.ApplicationsAudio Switching/MultiplexingPort ProtectionPower Management
