MAX20327
12V Capable, Low-RON,
Beyond-the-Rails™ DPDT Analog Switch
General Description
The MAX20327 ultra-small, low-on-resistance (RON)
double-pole/double-throw (DPDT) analog switches
feature Beyond-the-Rails™ capability that allows signals
from -5.5V to +12V to pass without distortion, even when
the power supply is below the signal range. The low onresistance (0.2Ω) also makes the devices ideal for lowdistortion switching applications, such as audio or video.
The MAX20327 is fully specified to operate from a
single +1.6V to +5.5V power supply. Because of the low
supply current requirement, VCC 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. The switches are
controlled with a single control bit, CB.
The MAX20327 is available in a 1.6mm x 1.6mm,
0.4mm pitch, 9-bump wafer-level package (WLP) and
operates over the -40°C to +85°C extended temperature
range.

MAX20327
12V Capable, Low-RON,
Beyond-the-Rails™ DPDT Analog Switch
Detailed Description
The MAX20327 is an ultra-small, low on-resistance, high
ESD-protected DPDT 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.
These switches feature the low on-resistance (RON)
necessary for high-performance switching applications.
The Beyond-the-Rails signal capability of the MAX20327
allows signals below ground and above VCC to pass
without distortion.
Analog Signal Levels
The MAX20327 is 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 MAX20327 provides a single-bit control logic input,
CB. CB controls the switch position, as shown in the
Typical Application Circuits.

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), ±8kV (Air-Gap Discharge), and ±6kV (Contact
Discharge) without damage. NO_ and NC_ are protected
against ESD up to ±2kV (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.
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 4 shows the Human Body Model. Figure 5 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 6 shows the IEC 61000-4-2 model
and Figure 7 shows the current waveform for the ±8kV,
IEC 61000-4-2, Level 4, ESD Contact-Discharge Method.
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,
