DG9408, DG9409
Vishay Siliconix
Precision 8-Ch/Dual 4-Ch Low Voltage Analog Multiplexers
DESCRIPTION
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-palladium-
gold 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.
FEATURES
• 2.7 V to 12 V single supply or ± 3 V to ± 6 V
