MAX4715/MAX4716
General Description
The MAX4715/MAX4716 are low on-resistance, lowvoltage, 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
switching speeds (tON = 18ns max, tOFF = 12ns max).
When powered from a +3V supply, the MAX4715/
MAX4716 offer 0.4Ω max on-resistance (RON) with 0.1Ω
max RON flatness. Their digital logic inputs are +1.8V
CMOS compatible when using a single +3V supply.
The MAX4715 is pin compatible with the MAX4594, and
the MAX4716 is pin compatible with the MAX4595. The
MAX4715/MAX4716 are available in SC70-5 packages.

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 = 20log10 [VCOM / (VNC or VNO)], VCOM = output, VNC or VNO = input to off switch.
Note 6: Guaranteed by design.

Typical Operating Characteristics (continued)
(TA = +25°C, unless otherwise noted.)
MAX4715/MAX4716
0.4Ω, Low-Voltage, Single-Supply
SPST Analog Switches in SC70
Detailed Description
The MAX4715/MAX4716 are low on-resistance (RON),
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).
When powered from a +3V supply, their 0.4Ω R ON
allows high continuous currents to be switched in a
variety of applications.
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.
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.
Applications Information
Logic Inputs
Rail-to-Rail is a registered trademark of Nippon Motorola Ltd.
The MAX4715/MAX4716 logic inputs can be driven up
to +3.6V regardless of the supply voltage. For example,
