SGM4157YC
SPDT 0.8Ω Analog Switch
GENERAL DESCRIPTION
The SGM4157YC is a single low on-resistance (0.8Ω),
fast single-pole double-throw (SPDT) CMOS switch. It is
designed for low operating voltage, high current
switching of speaker output for cell phone applications.
The SGM4157YC can handle a balanced microphone/
speaker/ring tone generator in a monophone mode. The
device contains a break−before−make (BBM) feature.
The control input, IN, tolerates input drive signals up to
5.5V, independent of supply voltage.
SGM4157YC is available in Green SC70-6 package.

NOTES:
1. Signals on NC, NO, or COM or IN 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 latest datasheet.
