... Rev 0; 10/02 4.5 Dual SPST Analog Switches in UCSP General Description The MAX4721/MAX4722/MAX4723 low-voltage, low on- resistance (R ), dual single-pole/single throw (SPST) ON analog switches operate from a single +1.8V to +5.5V supply. These devices are designed for USB 1.1 and audio switching applications. The MAX4721/MAX4722/MAX4723 feature 4.5 (max) with 1.2 flatness and 0.3 channels ...

... Preheating is required. Hand or wave soldering is not allowed. 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. ELECTRICAL CHARACTERISTICS— ...
