| DG2737, DG2738, DG2739 Vishay Siliconix 6-, Low Voltage, Dual SPST Analog Switch DESCRIPTION The DG2737, DG2738 and DG2739 are high performance, low on-resistance analog switches of dual SPST configuration. Built on Vishay Siliconix's sub-micro CMOS technology, the DG2737, DG2738, DG2739 achieve switch on-resistance of 6 at 3 V V+. Its - 3 dB bandwidth is typically 720 MHz. It can switch signals with amplitudes of up to VCC to be transmitted in either direction. Combining low power, high speed, low on-resistance and small physical size, the DG2737, DG2738, DG2739 are ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2737, DG2738, DG2739 come in a small miniQFN-8 lead package (1.4 x 1.4 x 0.55 mm). As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations and is 100 % RoHS compliant.

Typical values are for design aid only, not guaranteed nor subject to production testing. d. Guarantee by design, not subjected to production test. e. 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. Document Number: 68801 S-82643-Rev.
