Low-Voltage, Single-Supply Dual SPST/SPDT Analog Switches
General DescriptionThe 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, tOFF= 100ns max).
When powered from a +5V supply, the MAX4541–
MAX4544 offer 2Ωmax matching between channels, 60Ω
max on-resistance (RON), and 6Ωmax 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 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 QFN-8 pack-
ages, 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.

Applications Information
Logic LevelsThe MAX4541–MAX4544 are TTL compatible when
powered from a single +5V supply. When powered
from other supply voltages, TTL compatibility is guar-
anteed and the logic inputs can be driven Rail-to-Rail®.
For example, with a +12V supply, IN1 and IN2 can be
driven low to 0 and high to 12V. With a +3.3V supply,
IN1 and IN2 should be driven low to 0 and high to
3.3V.
Driving IN1 and IN2 rail-to-rail minimizes power con-
sumption.
Analog Signal LevelsAnalog signals that range over the entire supply voltage
(V+ to GND) can be switched with very little change in
on-resistance over the entire voltage range (see Typical
Operating Characteristics). All the switches are bidirec-
tional, so the NO_, NC_, and COM_ pins can be used
as either inputs or outputs.

Power-Supply Sequencing
and Overvoltage ProtectionDo not exceed the absolute maximum ratings because
stresses beyond the listed ratings may cause perma-
nent 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. If this sequenc-
ing is not possible, and if the analog or logic inputs are
not current limited to <10mA, add a small-signal diode
(D1) as shown in Figure 1. If the analog signal can dip
below GND, add D2. Adding protection diodes
reduces the analog signal range to a diode drop (about
0.7V) below V+ (for D1), and to a diode drop above
ground (for D2). Leakage is unaffected by adding the
diodes. On-resistance increases by a small amount at
low supply voltages. Maximum supply voltage (V+)
must not exceed 13V.
Adding protection diodes causes the logic thresholds
to be shifted relative to the power-supply rails. This can
be significant when low supply voltages (+5V or less)
are used. With a +5V supply, TTL compatibility is not
guaranteed when protection diodes are added. Driving
IN1 and IN2 all the way to the supply rails (i.e., to a
diode drop higher than the V+ pin, or to a diode drop
lower than the GND pin) is always acceptable.
Protection diodes D1 and D2 also protect against
some overvoltage situations. With Figure 1’s circuit, if
the supply voltage is below the absolute maximum rat-
ing, and if a fault voltage up to the absolute maximum
rating is applied to an analog signal pin, no damage
will result.
