| DG2735/DG2736 Vishay Siliconix Low Voltage, 0.6 , Dual SPDT Analog Switch DESCRIPTION The DG2735/2736 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 DG2735/2736 are ideal for portable and battery power applications. The DG2735/2736 have an operation range from 1.65 V to 4.3 V single supply. The DG2735 has two separate control pins with for the separated two SPDT switched. The DG2736 has an EN pin. All switches are at high impedance mode when the EN is high. The DG2735/2736 are guaranteed 1.65 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 DG2735/2736 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. DG2735/2736 are offered in a miniQFN package. The miniQFN package has a nickel-palladium-gold device termination and is represented by the lead (Pb)-free "-E4" suffix. The nickel-palladium-gold device terminations meet all JEDEC standards for reflow and MSL ratings.
