3.2 , Fast Switching Speed, +12 V / +5 V / +3 V / ± 5 V,
4- / 8-Channel Analog Multiplexers
DESCRIPTION
The DG9408E, DG9409E uses BiCMOS wafer fabrication
technology that allows the DG9408E, DG9409E to operate
on single and dual supplies. Single supply voltage
ranges from 3 V to 16 V while dual supply operation is
recommended with ± 3 V to ± 8 V.
The DG9408E 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
(A
0
, A
1
, A
2
). The DG9409E 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 (A
0
, A
1
). 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 DG9408E,
DG9409E 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.
