DESCRIPTION

The SP3222EB/SP3232EB series is an RSꢀ232 transceiver solution intended for portable or

handꢀheld applications such as notebook or laptop computers. The SP3222EB/SP3232EB

series has a highꢀefﬁciency, chargeꢀpump power supply that requires only 0.1ꢁF capacitors

in 3.3V operation. This charge pump allows the SP3222EB/SP3232EB series to deliver true

RSꢀ232performancefromasinglepowersupplyrangingfrom+3.0Vto+5.5V.TheSP3222EB/

SP3232EB are 2ꢀdriver/2ꢀreceiver devices. The ESD tolerance of the SP3222EB/SP3232EB

devices is over +/ꢀ15kV for both Human Body Model and IEC61000ꢀ4ꢀ2 Air discharge test

methods. The SP3222EB device has a lowꢀpower shutdown mode where the devices' driver

outputs and charge pumps are disabled. During shutdown, the supply current falls to less

than 1ꢁA.
