0.8Ω, Low-Voltage, Single-Supply
SPDT Analog Switch in SC70
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 (t
ON
= 18ns,
max, t
OFF
= 12ns, max).
When powered from a +3V supply, the MAX4714 fea-
tures 0.8Ω (max) on-resistance (R
ON
), with 0.18Ω (max)
R
ON
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.

Note 1:
Signals on NC, NO, and COM exceeding V+ or GND are clamped by internal diodes.
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:
Parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and
correlation.
Note 4:
Guaranteed by design for µDFN package.
Note 5:

Note 6:
Flatness is defined as the difference between the maximum and minimum values of on-resistance as measured over the
specified analog signal range.
Note 7:
