ON
double-pole/single throw (DPST) 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 on-
resistance (0.19Ω) also makes the devices ideal for low-
distortion switching applications, such as audio or video.

For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a “+”,
“#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing
pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.

Beyond-the-Rails DPST Analog Switches
Detailed Description
Applications Information
The MAX20336 is an ultra-small, low on-resistance, high
ESD-protected DPST switch that operates from a +1.6V
to +5.5V supply, and is designed to pass analog signals,
such as AC-biased or DC-biased audio and video signals.
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. COM_ and
NO_ are further protected against ESD up to ±30kV
(HBM), ±7kV (Air-Gap Discharge), and ±8kV (Contact
Discharge) without damage. The ESD structures with-
stand high ESD both in normal operation and when the
device is powered down. After an ESD event, the devices
continue to function without latchup.
These switches feature the low on-resistance (R
)
ON
necessary for high-performance switching applications.
The Beyond-the-Rails signal capability of the MAX20336
allows signals below ground and above V
without distortion.
to pass
CCEN
Analog Signal Levels
The MAX20336 is bidirectional, allowing NO_ and COM_
to be configured as either inputs or outputs. The topology
of the switches allows the signal to drop below ground
without the need of an external negative voltage supply.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents test
methodology and test results.
Digital Control Input
The MAX20336 combines enable and supply pins. The
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 1.5kΩ resistor.

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 5 shows the IEC 61000-4-2 model
and Figure 6 shows the current waveform for the ±8kV,
IEC 61000-4-2, Level 4, ESD Contact-Discharge Method.
IEC 61000-4-2
The IEC 61000-4-2 standard covers ESD testing and
performance of finished equipment. It does not
specifically 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,
