DG408DYZ

The DG408DYZ is a single 8-channel Monolithic CMOS Analogue Multiplexer is drop-in replacements for the popular DG508A and DG509A series devices. They each include an array of eight analogue 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 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 +5 to +34V or split from ±5 to ±20V. The analogue switches are bilateral, equally matched for AC or bidirectional signals.
