SP3232EH -3.3V, 460Kbps RS-232 Transceivers

The SP3222EU and the SP3232EU are 2 driver, 2 receiver RS-232 transceiver solutions intended 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-232 applications. Both ICs have a high-efficiency, charge-pump power supply that requires only 0.1 capacitors in 3.3V operation. This Charge Pump allows the SP3222EU and the SP3232EU to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The ESD tolerance of the SP3222EU SP3232EU devices are over ,5kV for both Human Body Model and IEC1000-4-2 Air discharge test methods. By Exar Corporation
