The DG9408, DG9409 uses BiCMOS wafer fabrication technology that allows the DG9408, DG9409 to operate on single and dual supplies. Single supply voltage ranges from 3 V to 12 V while dual supply operation is recommended with ± 3 V to ± 6 V. The DG9408 is an 8-channel single-ended analog multiplexer designed to connect one of eight inputs to a common output as determined by a 3-bit binary address (A0, A1, A2). The DG9409 is a dual 4-channel differential analog multiplexer designed to connect one of four differential inputs to a common dual output as determined by its 2-bit binary address (A0, A1). Break-before-make switching action to protect against momentary crosstalk between adjacent channels. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with lead (Pb)-free device terminations. The DG9408, DG9409 are offered in a QFN package that has a nickel-palladiumgold device terminations and is represented by the lead (Pb)-free “-E4” suffix. The nickel-palladium-gold device terminations meet all the JEDEC standards for reflow and MSL ratings.
