Renesas Electronics Corporation Monolithic, Quad SPST, CMOS Analog Switches DG441DVZ

The DG441 and DG442 monolithic CMOS analog switches are drop-in replacements for the popular DG201A and DG202 series devices. They include four independent single pole single throw (SPST) analog switches, TTL and CMOS compatible digital inputs, and a voltage reference for logic thresholds.brbr These switches feature lower analog ON resistance (85?) and faster switch time (tsubON/sub 250ns) compared to the DG201A and DG202. Charge injection has been reduced, simplifying sample and hold applications.brbr The improvements in the DG441 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 40VP-P signals. Power supplies may be single ended from +5V to +34V, symmetrical supplies from ±5V to ±22V or asymmetrical supplies limited to a maximum differential voltage of 44V with a V+ max of 34V or a V- max of -25V.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 DG441 and DG442 are identical, differing only in the polarity of the selection logic.
