DG2717 Vishay Siliconix Low-Voltage, 0.45-Ω, SPDT Analog Switch DESCRIPTION FEATURES The DG2717 is a low voltage, low on resistance, single- pole/ double-throw (SPDT) monolithic CMOS analog switch designed for high performance switching of analog signals. Combining low-power, high speed, low on-resistance, and small package size, the DG2717 is ideal for portable and battery power applications. • • • • • • The DG2717 has an operation range from 1.6 V to 4.3 V single supply, and is low voltage logic compatible within this range, allowing the easy interface with low voltage DSP or MCU control logic. These traits make it ideal for one cell Li-ion battery direct power. The switch conducts signals within power rails equally well in both directions when on, and blocks up to the power supply level when off. Break-before-make is guaranteed. The DG2717 is built on Vishay Siliconix’s sub micron CMOS low voltage process. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with lead (Pb)-free device terminations. For analog switching products manufactured in SC89 package, the lead (Pb)-free "E3" suffix is being used as a designator. It has a Tin device termination that meets all JEDEC standards for reflow and MSL rating. Low Voltage Operation (1.6 V to 4.3 V) Low On-Resistance - rDS(on): 0.45 Ω Typ.
