MAX4714
General Description
The MAX4714 is a low on-resistance, low-voltage single-pole/double-throw (SPDT) analog switch that operates from a single +1.6V to +3.6V supply. The
MAX4714 has break-before-make switching. This
device also has fast switching speeds (t ON = 18ns
max, tOFF = 12ns max).
When powered from a +3V supply, the MAX4714 features 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.

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 is 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: ∆RON = RON(MAX) - RON(MIN).
Note 5: Flatness is defined as the difference between the maximum and minimum values of on-resistance as measured over the
specified analog signal range.
Note 6: Guaranteed by design.
Note 7: Off-Isolation = 20log10 [VCOM / (VNC or VNO)], VCOM = output, VNC or VNO = input to off switch.
Note 8: Between the two switches.

Typical Operating Characteristics (continued)
(TA = +25°C, unless otherwise noted.)
MAX4714
0.8Ω, Low-Voltage, Single-Supply
SPDT Analog Switch in SC70
Detailed Description
The MAX4714 is a low-on-resistance (RON), low-voltage, 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 (t ON = 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.
+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.
Chip Information
Applications Information
Logic Inputs
The MAX4714 logic input can be driven up to +3.6V
regardless of the supply voltage. For example, with a
TRANSISTOR COUNT: 135
