General Description

The MAX4541–MAX4544 are precision, dual analog
switches designed to operate from a single +2.7V to
+12V supply. Low power consumption (5µW) makes
these parts ideal for battery-powered equipment. These
switches offer low leakage currents (100pA max) and fast
switching speeds (tON= 150ns max, t

OFF

= 100ns max).

When powered from a +5V supply, the MAX4541–
MAX4544 offer 2Ω max matching between channels, 60Ω
max on-resistance (RON), and 6Ω max RONflatness.

These switches also offer 5pC max charge injection and
a minimum of 2000V ESD protection per Method 3015.7.

The MAX4541/MAX4542/MAX4543 are dual single-pole/
single-throw (SPST) devices and the MAX4544 is a single­pole/double-throw (SPDT) device. The MAX4541 has two
normally open (NO) switches and the MAX4542 has two
normally closed (NC) switches. The MAX4543 has one NO
and one NC switch and can be used as an SPDT, while
the MAX4544 is an SPDT. The MAX4541/MAX4542/
MAX4543 are available in tiny SOT23-8 packages, and
the MAX4544 is available in a SOT23-6 package.

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.
