The DG2731/2732/2733 are low voltage, low on-resistance, dual single-pole/double-throw (SPDT) monolithic CMOS analog switches designed for high performance switching of analog signals. Combining low-power, high speed, low on-resistance, and small package size, the DG2731/2732/2733 are ideal for portable and battery power applications. The DG2731/2732/2733 have an operation range from 1.6 V to 4.3 V single supply. The DG2731 and DG2732 have two separate control pins with reverse control logic. The DG2733 has an EN pin to enable the device when the logic is high. The DG2731/2732/2733 are 1.6-V logic compatible, allowing the easy interface with low voltage DSP or MCU control logic and 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 DG2731/2732/2733 are built on Vishay Siliconix's sub micron CMOS low voltage process technology and provides greater than 300 mA latch-up protection, as tested per JESD78. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with lead (Pb)-free device terminations. DG2731/2732/ 2733 are offered in a DFN or MSOP package. The DFN package has a nickel-palladium-gold device termination and is represented by the lead (Pb)-free "-E4" suffix. The MSOP package uses 100% matte Tin device termination and is represented by the lead (Pb)- free "-E3" suffix. Both the matte Tin and nickel-palladium-gold device terminations meet all JEDEC standards for reflow and MSL ratings.
