The DG444 and DG445 monolithic CMOS analog switches are drop-in replacements for the popular DG211 and DG212 series devices. They include four independent single pole single throw (SPST) analog switches and TTL and CMOS compatible digital inputs.brbr These switches feature lower analog ON resistance (85?) and faster switch time (tsubON/sub 250ns) compared to the DG211 and DG212. Charge injection has been reduced, simplifying sample and hold applications.brbr The improvements in the DG444 series are made possible by using a high voltage silicon-gate process. An epitaxial layer prevents the latch-up associated with older CMOS technologies. The 44V maximum voltage range permits controlling ±20V signals when operating with ±20V power supplies.brbr The four 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. The switches in the DG444 and DG445 are identical, differing only in the polarity of the selection logic.
