SGM4581
High Voltage, CMOS Analog Multiplexer
GENERAL DESCRIPTION
The SGM4581 is a high voltage, CMOS analog IC
configured as an 8-channel multiplexer. This CMOS
device can operate from ±1.8V to ±5.5V dual power
supplies or from +3.6V to +11V single supplies. Each
switch can handle rail-to-rail analog signals. The
off-leakage current is only 10nA at +25℃.
All digital inputs have 0.8V to 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using a
single +5V or dual ±5V supplies.
SGM4581 is available in Green SOIC-16, SSOP-16,
TSSOP-16 and TQFN-3×3-16L packages. It operates
over an ambient temperature range of -40℃ to +85℃.

NOTES:
1. Voltages exceeding V
CC
or V
EE
on any signal terminal are
clamped by internal diodes. Limit forward-diode current to
maximum current rating.
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 latest datasheet.
