SP3243E
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 puters. The SP3243E includes one plementary 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 0.1µF capacitors for operation. This charge pump and Max Linear’s driver architecture allow the SP3243E series to deliver pliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The AUTO-ONLINE® feature allows the device to automatically “wake-up” during a shutdown state when an...
