SP3243E Data Sheet 3 Driver/5 Receiver Intelligent +3.0V to +5.5V RS-232 Transceivers General Description The SP3243E products (SP3243E, SP3243EB, SP3243EH, and SP3243EU) are 3 driver/5 receiver RS-232 transceiver solutions intended for portable or hand-held applications such as notebook and palmtop computers. The SP3243E includes one complementary receiver that remains alert to monitor an external device’s Ring Indicate signal while the device is shutdown. The SP3243E and EB devices feature slew-rate limited outputs for reduced crosstalk and EMI. The “EU” and “EH” series are optimized for high speed with data rates up to 1Mbps, easily meeting the demands of high speed RS-232 applications. The SP3243E series uses an internal high-efficiency charge-pump power supply that requires only 0.
