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 SC70-6 package.
