Beyond-the-Rails 16:2 Multiplexer

General Description

The MAX14661 is a serially controlled, dual-channel

analog multiplexer allowing any of the 16 pins to be

connected to either common pin simultaneously in any

combination. The device features Beyond-the-Rails

capability so that ±5.5V signals can be passed with any

single supply between +1.6V and +5.5V.

Features and Beneﬁts

●ꢀ Beyond-the-RailsꢀTechnologyꢀReducesꢀCostꢀandꢀ

Complexity

• Switch ±5.5V Signals from a +1.6V Single Supply

• Wide +1.6V to +5.5V Supply Range

• Low 5.5W R

(typ) Across the Supply Range

●ꢀ FlexibleꢀMultiplexingꢀEnablesꢀDesignꢀReuse

• 16:2 Matrix Switch Multiplexer Connects Any Input

Pin To Either Common Pin In Any Combination

The serial control is selectable between I C and SPI.

Both modes provide individual control of each indepen-

dent switch so that any combination of switches can

• Each Switch is Independently Controlled via I C or

SPI

be applied. I C mode provides two address-select pins

• Programmable Shadow Registers Allow

Simultaneous Updating

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.

Performance

The IC is available in a 28-pin (4mm x 4mm) TQFN pack-

age and is specified over the -40ºC to +85ºC extended

temperature range. The AB_ and COM_ pins provide

±10kV ESD protection (HBM).
