DescriptionThe SP3222EU and the SP3232EU are 2 driver, 2 receiver RS-232 transceiver solutionsintended for portable or hand-held applications such as notebook or palmtop computers.Their data transmission rate of 1000 kbps meets the demands of high speed RS-232applications. Both ICs have a high-efficiency, charge-pump power supply that requiresonly 0.1F capacitors in 3.3V operation. This charge pump allows they to deliver true RS-232 performance from a single power supply ranging from+3.0V to +5.5V. The ESD tolerance of the SP3222EU/3232EU devices are over ±15kVfor both Human Body Model and IEC1000-4-2 Air discharge test methods.
The SP3222EU device has a low-power shutdown mode where the devices' driveroutputs and charge pumps are disabled. During shutdown, the supply current falls to lessthan 1uA.
