描述 Description

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 0.1μF capacitors in 3.3V operation. This charge pump allows the SP3222EU and the 3232EU 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 ±15kV for both Human Body Model and IEC1000-4-2 Air discharge test methods.The SP3222EU device has a low-power shutdown mode where the devices' driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1uA.For technical support or help choosing a product please email Exar’s Serial Technical Support group at:?serialtechsupport@exar.com.
