SGM3699
0.5Ω, Low Voltage
Quad, SPDT Analog Switch
GENERAL DESCRIPTION
The SGM3699 is a quad, low on-resistance, low voltage,
bidirectional, single-pole/double-throw (SPDT) CMOS
analog switch that is designed to operate from a single
+1.8V to +4.2V power supply. Targeted applications
include battery powered equipment that benefit from low
R
ON
(0.5Ω) and fast switching speeds (t
ON
= 52ns, t
OFF
=
25ns).
The SGM3699 consists of four SPDT switches. It is
configured as a dual double-pole/double-throw (DPDT)
device with two logic control inputs that control two SPDT
switches each. The configuration can be used as a dual
differential 2-to-1 multiplexer/demultiplexer.
SGM3699 is available in Green TQFN-3×3-16L package.
FEATURES

NOTES:
1.
Signals on NC, NO, or COM or IN
X
exceeding V
+
will be
clamped by internal diodes. Limit forward diode current to
maximum current ratings.
2. 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.
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 last datasheet.
