The SGM4157 is a single Low on-resistance (1Ω), 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
SGM4157 can handle a balanced microphone/speaker
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. SGM4157YD6/TR资料下载
