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 SC70-6 package.

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.

(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.
