General Description
Benefits and Features
The MAX14589E/MAX14594E high-density, double-pole/
double-throw (DPDT) analog switches feature Beyond-
the-Rails™ capability that allows signals from -5.5V to
+5.5V to pass without distortion even when the power
supply is below the signal range. The low RON resistance
(0.2I) makes the devices ideal for low-distortion switch-
ing, such as audio.

ꢀClick-and-Pop Suppression
The MAX14594E has internal shunt switches that
discharge the audio amplifier AC-coupling capacitance
at the normally open (NO1 and NO2) terminals. This
feature reduces click-and-pop sounds that occur when
switching audio signals between precharged points.

When the power is not applied, switches go to a high-
impedance mode and all analog signal ports can with-
stand signals from -5.5V to +5.5V. The devices control
the switches with a control bit, CB.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion 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

Detailed Description
The MAX14589E/MAX14594E are low on-resistance
and high ESD-protected DPDT switches that operate
from a +1.6V to +5.5V supply and are designed to
multiplex AC-coupled analog signals. These switches
The shunt resistors are controlled by CB. When CB is low,
NC_ is connected to COM_ and NO_ is connected to the
shunt resistors. When CB is high, NO_ is connected to
COM_ and the shunt resistors are unconnected.

Rails signal capability of the analog channel allows

to pass through
CCEN
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), 10kV (Air-Gap Discharge), and 8kV
(Contact Discharge) without damage. NO_ and NC_ 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 devices continue to function
without latchup.
Analog Signal Levels
The devices are bidirectional, allowing NO_, NC_, and
COM_ to be configured as either inputs or outputs. The
topology of the internal switches allows the signal to
drop below ground without the need of an external nega-
tive voltage supply. Note: The devices can withstand
analog signal levels of -5.5V to +5.5V when the device
is not powered.
Digital Control Input
The devices provide a single-bit control logic input, CB.
CB controls the switch position, as shown in the Typical
Application Circuits/Functional Diagrams.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents test
methodology and test results.
Click-and-Pop Suppression
(MAX14594E Only)
The 500I shunt resistors automatically discharge any
capacitance at both NO_ terminals when they are not
connected to COM_. This reduces audio click-and-pop
Human Body Model
Figure 3 shows the Human Body Model. Figure 4 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 1.5kIresistor.

IEC 61000-4-2
The IEC 61000-4-2 standard covers ESD testing and
performance of finished equipment. It does not spe-
cifically refer to integrated circuits. The major difference
between tests done using the HBM and IEC 61000-4-2
is higher peak current in IEC 61000-4-2, because series
resistance is lower in the IEC 61000-4-2 model. Hence,
the ESD withstand voltage measured to IEC 61000-4-2
is generally lower than that measured using the HBM.
Figure 4 shows the IEC 61000-4-2 model and Figure 5
shows the current waveform for the 8kV, IEC 61000-4-2,
