® Data Sheet DG441, DG442 November 20, 2006 FN3281.10 Monolithic, Quad SPST, CMOS Analog Switches 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 patible digital inputs, and a voltage reference for logic thresholds. These switches feature lower analog ON resistance (<85Ω) and faster switch time (tON <250ns) pared to the DG201A and DG202. Charge injection has been reduced, simplifying sample and hold applications. 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...
