$Features & Applications
The SP3243 products are 3 driver/5 receiver RS-232 transceiver solutions intended for portable or handheld applications such as notebook and palmtop computers.
The SP3243 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 "U" and "H" series are optimized for high speed with data rates up to 1Mbps, easily meeting the demands of high speed RS-232 applications.
The SP3243 series uses an internal high-efficiency, charge-pump power supply that requires only 0.1μF capacitors in 3.3V operation. This charge pump and Exar's driver architecture allow the SP3243 series to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V.
The AUTO ON-LINE® 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.
- Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply
- ±15kV ESD protection
- 1Mbps Data rate
- AUTO ON-LINE® circuitry automatically wakes up from a 1µA shutdown
- Regulated Charge Pump Yields Stable RS-232 Outputs Regardless of VCC Variations
- Enhanced ESD Specifications:
- ±15kV Human Body Model
- ±15kV IEC1000-4-2 Air Discharge
- ±8kV IEC1000-4-2 Contact Discharge
- 250 Kbps min. transmission rate (EB)
- 1000 Kbps min. transmission rate (EU)
- Ideal for High Speed RS-232 Applications
Exar’s SP3243EU product family are a series of High Speed Intelligent +3.0V to +5.5V RS-232 Transceivers.
