DESCRIPTION
The DG9408/9409 uses BiCMOS wafer fabrication
technology that allows the DG9408/9409 to operate on
single and dual supplies. Single supply voltage ranges from
3 to 12 V while dual supply operation is recommended with
± 3 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 DG9408/9409
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.
