Single 8-Channel/Differential 4-Channel, CMOS Analog Multiplexers

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.
The DG408 and DG409 feature lower signal ON resistance (<100) 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 5V to 20V.
The Analog Switches are bilateral, equally matched for AC or bidirectional signals. The ON resistance variation with Analog signals is quite low over a 5V Analog input range.
