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 (tON= 18ns,
max, t
OFF
= 12ns, max).
When powered from a +3V supply, the MAX4714 features 0.8Ω (max) on-resistance (RON), with 0.18Ω (max)
RONmatching 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.
