MAX14760/MAX14762/MAX14764
Above- and Below-the-Rails
Low-Leakage Analog Switches
General Description
The MAX14760/MAX14762/MAX14764 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 MAX14760 is a single-pole/single-throw (SPST) analog switch, while the MAX14762 is a dual-SPST analog
switch. The MAX14764 is a single-pole/double-throw
(SPDT) analog switch.
The MAX14760/MAX14762/MAX14764 feature 20I (max)
on-resistance with a Q10nA (max) on-leakage current for
MAX14760/MAX14762.
The MAX14760/MAX14764 are available in 8-pin (3mm x
3mm) TDFN packages. The MAX14762 is available in a
10-pin (3mm x 3mm) TDFN package. These devices are
specified over the -40NC to +85NC extended operating
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 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.
