DATASHEET DG408, DG409 FN3283 Rev 8.00 Single 8-Channel/Differential 4-Channel, CMOS Analog Multiplexers Jun 13, 2006 The DG408 Single 8-Channel, and DG409 Differential Features 4-Channel monolithic CMOS analog multiplexers are drop-in ON Resistance (Max, 25C) . 100 replacements for the popular DG508A and DG509A series devices. They each include an array of eight analog Low Power Consumption (P ) .<11mW D switches, a TTL/CMOS compatible digital decode circuit for Fast Switching Action channel selection, a voltage reference for logic thresholds -t <250ns TRANS and an ENABLE input for device selection when several -t <150ns ON/OFF(EN) multiplexers are present. Low Charge Injection The DG408 and DG409 feature lower signal ON resistance (<100) and faster switch transition time (t < 250ns) Upgrade from DG508A/DG509A TRANS compared to the DG508A or DG509A. Charge injection has TTL, CMOS Compatible been reduced, simplifying sample and hold applications. The Single or Split Supply Operation improvements in the DG408 series are made possible by using a high-voltage silicon-gate process. An epitaxial layer Pb-Free Plus Anneal Available (RoHS Compliant) prevents the latch-up associated with older CMOS technologies. Power supplies may be single-ended from +5V Applications to +34V, or split from 5V to 20V. Data Acquisition Systems The analog switches are bilateral, equally matched for AC or Audio Switching Systems bidirectional signals. The ON resistance variation with Automatic Testers analog signals is quite low over a 5V analog input range.

They are not intended for use in Reflow solder processing applications. NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
