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.
The SGM4157YC is available in a Green SC70-6
package.

ABSOLUTE MAXIMUM RATINGS
OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.
RECOMMENDED OPERATING CONDITIONS
Operating Temperature Range ....................... -40℃ to +85℃
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.
ESD SENSITIVITY CAUTION
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
