MAX14761
MAX14759/MAX14761/MAX14763
Above- and Below-the-Rails
Low On-Resistance Analog Switches
General Description
The MAX14759/MAX14761/MAX14763 analog switches
are capable of passing bipolar signals that are beyond
their supply rails. These devices operate from a single
+3.0V to +5.5V supply and support signals in the -25V
to +25V range.
The MAX14759 is a single-pole/single-throw (SPST) ana-
log switch, while the MAX14761 is a dual-SPST analog
switch. The MAX14763 is a single-pole/double-throw
(SPDT) analog switch.
The MAX14759 features 1I (max) on-resistance with
a Q200nA (max) on-leakage current. The MAX14761/
MAX14763 feature 2I (max) on-resistance with a Q100nA
(max) on-leakage current. The low on-resistance and
high bandwidth allow use in digital- and analog-signal
switching applications.
The MAX14759/MAX14763 are available in an 8-pin
(3mm x 3mm) TDFN package. The MAX14761 is avail-
able in a 10-pin (3mm x 3mm) TDFN package. These
devices are specified over the -40NC to +85NC extended
temperature range.
Ordering Information/Selector Guide appears at end of data
sheet.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion 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.
