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 (<100R) 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.
