General Description
The MAX14535E–MAX14539E are low on-resistance
and high ESD-protected DPDT switches that multiplex
analog signals, such as AC-coupled audio or video.
These devices combine the low on-capacitance (C
ON
)
and low on-resistance (RON) necessary for high-performance switching applications in portable electronics,
and include an internal negative supply to pass audio
signals that swing below ground (down to -1.5V).
The MAX14535E/MAX14537E/MAX14539E feature internal shunt resistors on the normally open path (and normally closed path, (MAX14539E)) to reduce clicks and
pops heard at the output. The MAX14535E–
MAX14539E have an enable input (EN) to reduce supply current and set all channels to high-impedance
when driven low. When EN is driven low, the
MAX14537E/MAX14538E have the lowest possible current consumption, but cannot withstand negative rail
signals. The MAX14535E/MAX14536E/MAX14539E can
still withstand a negative signal to NC_, NO_, or COM_
from -1.5V to min (VCC, 3V.)
The MAX14535E–MAX14539E operate from a +2.4V to
+5.5V supply. These devices can be powered from the
typical analog supply voltage in a cell phone (+2.5V to
+2.8V) or a lithium-ion (Li+) battery (about 4.3V max).
The MAX14535E–MAX14539E have high ESD protection, up to ±15kV on COM_, and the NC_, NO_, and
COM_ voltage can go up to 3.6V when V
CC
= 0 without
damaging the devices.
All devices are offered in a space-saving, 10-pin,
1.4mm x 1.8mm UTQFN package, and operate over the
-40°C to +85°C extended temperature range.

(VCC= +2.4V to +5.5V, TA= -40°C to +85°C, unless otherwise noted. Typical values are at VCC= +3.0V, TA= +25°C.) (Note 2)
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.
Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7 using a four-
layer board. For detailed information on package thermal considerations, refer to www.maxim-ic/thermal-tutorial

Low-Resistance DPDT Switches
with Negative Rail
_______________________________________________________________________________________ 7
Pin Description
Detailed Description
The MAX14535E–MAX14539E are low on-resistance
and high ESD-protected single DPDT switches that
operate from a +2.4V to +5.5V supply and are
designed to multiplex AC-coupled analog signals.
These switches combine the low on-capacitance (CON)
and low on-resistance (RON) necessary for high-performance switching applications. The negative signal
capability of the analog channel allows signals below
ground to pass through without distortion.
Analog Signal Levels
The MAX14535E−MAX14539E are bidirectional, allowing NO_, NC_, and COM_ to be configured as either
inputs or outputs. Note that NC_ and NO_ are only protected against ESD up to ±2kV (Human Body Model)
and may require additional ESD protection if used as
outputs. These devices feature a charge pump that
generates a negative supply to allow analog signals as
low as -1.5V to pass through NO_, NC_, or COM_. This
allows AC-coupled signals that drop below ground to
pass even when operating from a 3.0V to 5.5V supply.
For the MAX14537E/MAX14538E, the negative charge
pump is controlled by the enable input and is active
when EN is high. When EN is driven low, the negative
charge pump is disabled, which puts the devices in the
lowest possible current consumption, and the signal
range is 0 to VCC. The negative charge pump is always
active for the MAX14535E/MAX14536E/MAX14539E,
therefore, a negative signal (at most -1.5V) can be
applied through NC_, NO_, or COM_, even when EN is
driven low. A negative rail signal (signal voltage < 0)
must not be applied to the switch unless the negative
charge pump is active.
Digital Control Input
The MAX14535E−MAX14539E provide a single-bit control logic input, CB. CB controls the switch position as
shown in the
Functional Diagrams
. Drive CB rail-to-rail
to minimize power consumption.
Enable Input
The MAX14535E−MAX14539E feature a shutdown
mode that reduces the supply current (less than 1µA
for MAX14537E/MAX14538E) and places the switches
in high impedance. Drive EN low to place the device in
shutdown mode. Drive EN high for normal operation.
Shunt Resistors
(MAX14535E/MAX14537E/MAX14539E)
When EN is high, the shunt resistors are controlled by
CB. When CB is low, NC_ is connected to COM_ and
NO_ is connected to shunt resistors. When CB is high,
NO_ is connected to COM_ and NC_ is connected to
shunt resistors (MAX14539E). When EN is low, all the
switches are open and all the shunt resistors are active.
Click-and-Pop Suppression
The 500Ω shunt resistors on the MAX14535E/
MAX14537E/MAX14539E automatically discharge any
capacitance at the NO_ terminals (or NC_ terminals,
MAX14539E) when they are unconnected from COM_.
This reduces audio click-and-pop sounds that may
occur when switching between capacitively coupled
audio sources.

Applications Information
Extended ESD Protection
ESD protection structures are incorporated on all pins
to protect against electrostatic discharges up to ±2kV
(HBM) encountered during handling and assembly.
COM1 and COM2 are further protected against ESD
up to ±15kV (HBM) without damage. The ESD structures withstand high ESD both in normal operation and
when the device is powered down. After an ESD event,
the MAX14535E−MAX14539E continue to function without latchup.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test setup, test methodology, and test results.
Human Body Model
Figure 3a shows the Human Body Model. Figure 3b shows
the current waveform it generates when discharged into
a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest that is then
discharged into the device through a 1.5kΩ resistor.
IEC 61000-4-2
The main difference between tests done using the
Human Body Model and IEC 61000-4-2 is higher peak
current in the IEC 61000-4-2. Because series resistance
is lower in the IEC 61000-4-2 ESD test model (Figure
3c) the ESD withstand voltage measured using the
Human Body Model. Figure 3d shows the current waveform for the ±8kV IEC 61000-4-2 Level 4 ESD Contact
Discharge test.
The Air-Gap Discharge test involves approaching the
device with a charged probe. The Contact Discharge
method connects the probe to the device before the
probe is energized.

Power-Supply Sequencing
Caution: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings
may cause permanent damage to the device.
Proper power-supply sequencing is recommended for
all devices. Apply V
CC
before applying analog signals,
especially if the analog signal is not current limited.
