| DG447/448 Vishay Siliconix Low Power, High Voltage SPST Analog Switches DESCRIPTION The DG447 and DG448 are dual supply single-pole/singlethrow (SPST) switches. On resistance is 25 maximum and flatness is 2.2 max over the specified analog signal range. These analog switches were designed to provide high speed, low error switching of precision analog signals. The primary application areas are in the routing and switching in telecommunications and test equipment. Combining low power, low leakages, low on-resistance and small physical size, the DG477/448 are also ideally suited for portable and battery powered industrial and military equipment. The DG477 has one normally closed switch, while the DG448 switch is normally open. They operate either from a single + 7 V to 36 V supply or from dual 4.5 V to 20 V supplies. They are offered in the very popular, small T6SOP6 package.

Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet. e. Guaranteed by design, not subject to production test. f. VIN = input voltage to perform proper function. 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. www.vishay.com 4 Document Number: 73854 S-62352-Rev.
