DG508B, DG509B  
Vishay Siliconix  
Precision 8-Channel/Dual 4-Channel CMOS Analog Multiplexers  
DESCRIPTION  
FEATURES  
The DG508B 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 DG509B 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 protects against momentary crosstalk between  
adjacent channels.  
An on channel conducts current equally well in both  
directions. In the off state each channel blocks voltages up  
to the power supply rails. An enable (EN) function allows the  
user to reset the multiplexer/demultiplexer to all switches off  
for stacking several devices. All control inputs, addresses  
(Ax) and enable (EN) are TTL compatible over the full  
specified operating temperature range.  
Operate with single or dual power supply  
V+ to V- analog signal swing range  
44 V power supply maximum rating  
Extended operate temperature range:  
- 40 °C to + 125 °C  
Low leakage typically < 3 pA  
Low charge injection - Q  
= 2 pC  
INJ  
Low power - ISUPPLY: 10 µA  
TTL compatible logic  
> 250 mA latch up current per JESD78  
Available in SOIC16, TSSOP16, PDIP, and miniQFN16  
packages  
Superior alternative to:  
- ADG508A, DG508A, HI-508  
- ADG509A, DG509A, HI-509  
Compliant to RoHS Directive 2002/95/EC  
Halogen-free according to IEC 61249-2-21 definition  
The DG508B and DG509B are fabricated on an enhanced  
SG-II CMOS process that achieves improved performance  
on: reduced charge injection, lower device leakage, and  
minimized parasitic capacitance.  
As the DG508, DG509 has a long history in the industry with  
many suppliers offering copies - and in some cases  
improved variations - with the best in class improvements,  
the Vishay Siliconix new version of the DG508B, DG509B  
are the superior alternatives to what is currently available.  
Applications for the DG508B, DG509B include high speed  
and high precision data acquisition, audio signal switching  
and routing, ATE systems, and avionics. High performance  
and low power dissipation make them ideal for battery  
operated and remote instrumentation applications.  
The DG508B and DG509B have the absolute maximum  
voltage rating extended to 44 V. Additionally, single supply  
operation is also allowed. An epitaxial layer prevents  
latch-up.  
BENEFITS  
Reduced switching errors  
Reduced glitching  
Improved data throughput  
Reduced power consumption  
Increased ruggedness  
Wide supply ranges ( 5 V to 20 V)  
APPLICATIONS  
Data acquisition systems  
Audio and video signal routing  
ATE systems  
Medical instrumentation  
FUNCTIONAL BLOCK DIAGRAM AND PIN  
CONFIGURATION  
The DG508B and DG509B are both available in 16-lead  
SOIC, TSSOP, PDIP, and miniQFN (1.8 mm x 2.6 mm)  
package options with extended temperature range of - 40 °C  
to + 125 °C.
