The SP3223EB and SP3243EB use an internal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3223EB/3243EB series to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The SP3223EB is a 2-driver/2-receiver device, and the SP3243EB is a 3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications. The SP3243EB includes one complementary receiver that remains alert to monitor an external device's Ring Indicate signal while t...
