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.
