The SP208EH/211EH/213EH devices are high speed enhanced multi-channel
RS-232 line transceivers with improved electrical performance. The
SP208EH/211EH/213EH series is a superior drop-in replacement to our
previous versions as well as popular industry standards. All devices
feature very low power CMOS construction and the MaxLinear-patented
(5,306,954) on-board charge pump circuitry that generates the +/-10V
RS-232 voltage levels using 0.1μF charge pump capacitors. The SP211EH
and SP213EH devices feature a low-power shutdown mode, which reduces
power supply drain to 1μA. Enhancements to this series include a higher
transmission rate of 500kbps, a lower power supply current at 3mA
typical (no load), and superior ESD performance. The ESD tolerance has
been improved for this series to over +/-15kV for both Human Body Model
and IEC61000-4-2 Air Discharge test methods.
- Single +5V Supply Operation
- 0.1μF External Charge Pump Capacitors
- 500Kbps Data Rate Under Load
- Standard SOIC and SSOP Packages
- Lower Supply Current Than Competition (typical 3mA)
- 1uA Shutdown Mode
- Wakeup Feature in Shutdown Mode
- Tri–State Receiver Outputs
- Ideal for High Speed RS-232 Applications
- Improved ESD Specifications:
- ±15kV Human Body Model
- ±15kV IEC1000-4-2 Air Discharge
- ±8kV IEC1000-4-2 Contact Discharge

For RS-232 it is 50 feet (15 meters), or the cable length equal to a capacitance of 2500 pF, at a maximum transmission rate of 19.2kbps. When we reduce the baud rate, it allows for longer cable length. For Example:
Baud Rate (bps)
Maximum RS-232 Cable Length (ft)
