0.4Ω, Low-Voltage, Single-Supply
SPST Analog Switches in SC70
General Description
Benefits and Features
The MAX4715/MAX4716 are low on-resistance, low-
voltage, single-pole/single-throw (SPST) analog switches
that operate from a +1.6V to +3.6V single supply. The
MAX4715 is normally open (NO), and the MAX4716
is normally closed (NC). These devices also have fast

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.

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.
Note 3: SC70-packaged parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and
correlation.
Note 4: Flatness is defined as the difference between the maximum and minimum values of on-resistance as measured over the
specified analog signal range.
Note 5: Off-Isolation = 20log [V

0.4Ω, Low-Voltage, Single-Supply
SPST Analog Switches in SC70
with a +3.3V supply, IN may be driven low to GND and
high to +3.6V. Driving IN Rail-to-Rail minimizes power
consumption.
Detailed Description
The MAX4715/MAX4716 are low on-resistance (R ),
low-voltage, single-pole/single-throw (SPST) analog
switches that operate from a +1.6V to +3.6V single
supply. The MAX4715 is normally open (NO), and the
MAX4716 is normally closed (NC).
®
ON
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 the Typical Operating Characteristics
section). The switches are bidirectional, so the NO, NC,
and COM pins can be used as either inputs or outputs.
When powered from a +3V supply, their 0.4Ω R
high continuous currents to be switched in a variety of
applications.

Applications Information
Logic Inputs
The MAX4715/MAX4716 logic inputs can be driven up
to +3.6V regardless of the supply voltage. For example,
