EVALUATION KIT AVAILABLE MAX14662 Beyond-the-Rails 8 x SPST General Description Features and Benefits 8 x SPST Switch The MAX14662 is a serially controlled 8 x SPST switch for general purpose signal switching applications. The num- Serial Control ber of switches makes the device useful in a wide variety 2 I C with Two Address-Select Pins of applications while serial control maximizes flexibility SPI with DOUT for Daisy Chain with minimal pins. This part features Beyond-The-Rails Independent Control of Each Switch capability so that 5.5V signals can be passed with any single supply between +1.6V and +5.5V. Beyond-the-Rails 2 5.5V Signal Range Independent of Supply The serial control is selectable between I C and SPI. Voltage Both modes provide individual control of each indepen- dent switch so that any combination of switches can be Low Distortion Switching 2 applied. I C mode provides two address select pins allow- Total Harmonic Distortion + Noise 0.001% (typ) ing for addressing up to four devices on a single bus. The R Flatness 0.5m (typ) Across Complete SPI mode includes a DOUT pin that can be used to chain ON Signal Range multiple devices together with a single select signal. Wide Supply Range The MAX14662 is available in a 28-pin (4mm x 4mm) TQFN package and is specified over the -40C to +85C +1.6V to +5.5V Single Supply extended temperature range. The A and B pins provide 0.425 R (typ) ON 15kV Human Body Model (HBM) ESD protection.
