SGM3717
4Ω, 400MHz Bandwidth, Dual, SPDT
Negative Signal Handling Analog Switch
GENERAL DESCRIPTION
The SGM3717 is a dual, bidirectional, single-pole/
double-throw (SPDT) CMOS analog switch designed to
operate from a single +2.5V to +5.0V supply. It features
high bandwidth (400MHz) and low on-resistance (4Ω
TYP), and the switches can handle negative signal
down to -2.0V.

FEATURES
Supply Range: +2.5V to +5.0V
Negative Signal Swing Capability: -2.0V to V
+
On-Resistance: 4Ω (TYP) at +5.0V
High Bandwidth: 400MHz
Fast Switching Times
t
ON
= 15ns (TYP)

OFF
= 11ns (TYP)
High Off-Isolation: -49dB at 10MHz
Low Crosstalk: -52dB at 10MHz
1.8V Logic Control
Break-Before-Make Switching
Extended Industrial Temperature Range:
-40℃ to +85℃
Small Package
Available in Green UTQFN-1.8×1.4-10L Package
matching of 0.15Ω (TYP) between switches and a
guaranteed on-resistance flatness of 1.5Ω (TYP) over
the signal range. This ensures excellent linearity and
low distortion when switching audio signals.
The SGM3717 is a committed dual single-pole/
double-throw (SPDT) switch that consists of two
normally open (NO) and two normally closed (NC)
switches. This configuration can be used as a dual
2-to-1 multiplexer.
APPLICATIONS
Portable Instrumentation
Battery-Operated Equipment
Computer Peripherals
Cell Phones
PDAs
MP3s
SGM3717 is available in UTQFN-1.8×1.4-10L package.

NOTES:
1. 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.
2. Signals on NC, NO, or COM or IN exceeding V
+
will be
clamped by internal diodes. Limit forward diode current to
maximum current ratings.
CAUTION
This integrated circuit can be damaged by ESD if you don’t pay
attention to ESD protection. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because
very small parametric changes could cause the device not to
meet its published specifications.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get
the latest datasheet.
