General Description
The MAX4714 is a low on-resistance, low-voltage sin-
gle-pole/double-throw (SPDT) analog switch that oper-
ates from a single +1.6V to +3.6V supply. The
MAX4714 has break-before-make switching. This
device also has fast switching speeds (tON = 18ns,
max, tOFF = 12ns, max).
When powered from a +3V supply, the MAX4714 fea-
tures 0.8Ω(max) on-resistance (RON), with 0.18Ω(max)
RON matching and flatness. The digital logic input is 1.8V
CMOS compatible when using a single +3V supply.
The MAX4714 is pin compatible with the MAX4599 and
is available in a 6-pin SC70 or µDFN package.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Detailed Description
The MAX4714 is a low-on-resistance (RON), low-volt-
age, single-pole/double-throw (SPDT) analog switch
that operates from a +1.6V to +3.6V supply. The
MAX4714 has break-before-make switching. This
device also has fast switching speeds (tON = 18ns,
max, tOFF = 12ns, max).
When powered from a +3V supply, the 0.8Ω(max) RON
allows high continuous currents to be switched in a
variety of applications.
Applications Information
Logic Inputs
The MAX4714 logic input can be driven up to +3.6V
regardless of the supply voltage. For example, with a
+3.3V supply, IN may be driven low to GND and high to
+3.6V. Driving IN rail-to-rail minimizes power consump-
tion.
Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) can be passed with very little change in
on-resistance (see Typical Operating Characteristics).
The switches are bidirectional, so the NO, NC, and
COM pins can be used as either inputs or outputs.
