EVALUATION KIT AVAILABLE
Beyond-the-Rails 8 x SPST
General Description
The MAX14662 is a serially controlled 8 x SPST switch for
general purpose signal switching applications. The num-
ber 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 indepen-
dent switch so that any combination of switches can be
applied. I2C mode provides two address select pins allow-
ing 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.
