FEATURES
■ Meets true EIA/TIA-232-F Standards
■ Interoperable with EIA/TIA-232 and
■ AUTO ON-LINE
■ Regulated Charge Pump Yields Stable
■ Enhanced ESD Specifications:
■ 250 Kbps min. transmission rate (EB)
■ 1000 Kbps min. transmission rate (EU)
■ Ideal for High Speed RS-232 Applications
The SP3243 products are 3 driver/5 receiver RS-232 transceiver solutions intended for portable or hand-
held 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
Sipex'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
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.
