DESCRIPTION

TheSP3220E devicesareRS-232driver/receiversolutionsintendedforportableorhand-held

applications such as palmtop computers, instrumentation and consumer products. These

devices incorporate a high-efficiency charge-pump power supply that allows theSP3220E

devicestodelivertrueRS-232performancefromasinglepowersupplyrangingfrom+3.0V

to +5.0V. This charge pump requires only 0.1µF capacitors in 3.3V operation. The ESD

toleranceofthesedevicesisover±15kVforbothHumanModelandIEC1000-4-2Airdischarge

test methods. All devices have a low-power shutdown mode where the driver outputs and

chargepumpsaredisabled.Duringshutdown,thesupplycurrentfallstolessthan1µA.
