General Description

The MAX4711/MAX4712/MAX4713 are fault-protected,

on-resistance and guaranteed on-resistance flatness over

the specified signal range. Due to the fault protection fea-

ture the analog switch input (NO_ or NC_) and output

(COM_) pins are not symmetrical. The fault protection fea-

ture allows for the analog input to go beyond the plus or

minus supplies without the device drawing excessive

amounts of current from the analog inputs. When the ana-

log inputs are driven beyond the supply rails when the

switch is on, it will sense a fault and turn itself off and the

analog switch output will be clamped to the same polarity

supply as the input signal and will not go beyond the sup-

ply rails. This feature protects any electronic circuitry con-

nected to the output from excessive voltages present on

the analog inputs.

The MAX4711/MAX4712/MAX4713 are quad, single-

pole/single-throw (SPST) analog switches. The MAX4711

has four normally closed switches (NC), the MAX4712 has

four normally open switches (NO), and the MAX4713 has

two NO and two NC switches. Switching times are less

switches operate from a single +2.7V to +11V supply or

from dual ±2.7V to ±5.5V supplies. All digital inputs have

+0.8V to +2.4V logic thresholds, ensuring both TTL and

CMOS logic compatibility when using ±4.5V to ±5.5V or

single +4.5V to +11V supplies.
