Overview
The MAX4594DCKR is a single-pole single-throw (SPST) analog switch designed by Texas Instruments. This device operates from a supply voltage range of 2 V to 5.5 V, making it versatile for various applications. It can handle both digital and analog signals, allowing signals up to V+ to be transmitted in either direction. The MAX4594DCKR is packaged in a 5-pin SC-70 package and is suitable for a wide range of operating temperatures from -40°C to 85°C.
