MAX20336/MAX20337
Ultra-Small, Low-RON, Beyond-the-Rails
DPST/SPDT Analog Switches
General Description
Benefits and Features
The MAX20336/MAX20337 ultra-small, low-on-resistance
(RON) double-pole/single throw (DPST) and single-pole/
double-throw (SPDT) analog switches feature Beyondthe-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.
● Distortion-Free Beyond-the-Rails Signaling
• Negative Voltage Audio and Video Signal Capable
• -5.5V to +5.5V Analog Signal Range Independent
of VCCEN
• On-Resistance 0.19Ω (typ)
• +1.6V to +5.5V Single-Supply Range
• Total Harmonic Distortion Plus Noise -114dB (typ)
• On-Resistance Flatness 0.0001Ω (typ)
The MAX20336/MAX20337 are fully specified to operate
from a single +1.6V to +5.5V power supply. Because of
the low supply current requirement, VCCEN can be provided by a GPIO. When power is not applied, the switches go
to a high-impedance mode and all analog signal ports can
withstand signals from -5.5V to +5.5V.
● Low Supply Current 65μA/70μA (typ) at 1.6V
• Can be Powered by GPIO
• High-Impedance Mode when VCCEN Not Applied
The MAX20336/MAX20337 are available in a 1.308mm
x 0.828mm, 0.4mm pitch, 6-bump wafer-level package
(WLP) and 1.25mm x 1.75mm 6-pin FC2QFN package,
and operate over the -40°C to +85°C extended temperature range.

MAX20336/MAX20337
Ultra-Small, Low-RON, Beyond-the-Rails
DPST/SPDT Analog Switches
Detailed Description
The MAX20336/MAX20337 are ultra-small, low on-resistance, high ESD-protected DPST/SPDT switches that operate
from a +1.6V to +5.5V supply, and are designed to pass analog signals, such as AC-biased or DC-biased audio and video
signals. These switches feature the low on-resistance (RON) necessary for high-performance switching applications. The
Beyond-the-Rails signal capability of the MAX20336/MAX20337 allows signals below ground and above VCCEN to pass
without distortion.
Analog Signal Levels
The MAX20336/MAX20337 are bidirectional, allowing NO_, NC 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.
Digital Control Input
The MAX20336 combines enable and supply pins. The switches are on when the device is powered. Connect VCCEN to
GND to turn off the switches.
The MAX20337 has a control bit (CB). COM is connected to NC when CB is low, and connected to NO when CB is high.
Connect VCCEN to GND to turn off the switches.

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. COM_, NC and NO_ are further protected against ESD up to ±30kV (HBM),
±7kV (Air-Gap Discharge), and ±8kV (Contact Discharge) 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.
ESD Test Conditions
ESD performance depends on a variety of conditions. Contact Maxim for a reliability report that documents test
methodology and test results.
Human Body Model
Figure 5 shows the Human Body Model. Figure 6 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 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, 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 7 shows the IEC 61000-4-2
model and Figure 8 shows the current waveform for the ±8kV, IEC 61000-4-2, Level 4, ESD Contact-Discharge Method.
