SP3243E Datasheet | MaxLinear

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 RS-232 cable is connected and a connected peripheral is turned on. Otherwise, the device automatically shuts itself down, drawing less than 1µA. Features - Meets true EIA/TIA-232-F standards from a +3.0V to +5.5V power supply - Interoperable with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.7V power source - AUTO-ONLINE® circuitry automatically wakes up from a 1µA shutdown - Regulated Charge Pump yields stable RS-232 outputs regardless of VCC variations - Enhanced ESD specifications:  ±15k V Human Body Model  ±15k V IEC61000-4-2 Air Discharge  ±8k V IEC61000-4-2 Contact Discharge - 250kbps minimum transmission rate (EB) - 1000kbps minimum transmission rate (EU) - Ideal for high speed RS-232 applications Ordering Information - page 23 Selection Table Table 1: SP3243E Selection Table Device SP3243E SP3243EB SP3243EH SP3243EU Power Supplies RS-232 Drivers +3.0V to +5.5V 3 +3.0V to +5.5V 3 +3.0V to +5.5V 3 +3.0V to +5.5V 3 RS-232 External Receivers ponents 4...
