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 (t

= 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 (R

), and 6Ω max R

flatness.

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 single-

pole/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 and 8-pin TDFN packages,

and the MAX4544 is available in a SOT23-6 package.

Low-Voltage, Single-Supply Dual SPST/SPDT Analog Switches Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the devices. Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals or logic inputs, especially if the analog or logic signals are not current limited.
