    Rev 1.00
    Jun 4, 2007 Monolithic, Quad SPST, CMOS Analog Switches
    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.
    These switches feature lower analog ON resistance (<85)
    and faster switch time (tON <250ns) compared to the DG211
    and DG212. Charge injection has been reduced, simplifying
    sample and hold applications.
    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.
    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, ...
