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