The MAX211CWI+ is a +5V, RS232 transceiver with four 0.1μF external capacitors in 28 pin WSOIC package. It is a RS232 and V.28 transceiver with integrated charge pump circuitry for single +5V supply operation. It consists of three sections such as charge pump voltage converters, drivers (transmitters) and receivers. The integrated charge pump circuitry eliminates the need for bipolar ±12V supply and enables single supply operation from +5V or 9V to +12V. The driver maintains the ±5V EIA/TIA-232E output signal levels at data rates in excess of 120Kbps when loaded in accordance with the EIA/TIA-232E specification.
Supply voltage range from 4.5V to 5.5V
Operating temperature range from 0°C to 70°C
Saves board space
VCC power supply current of 11mA
Four RS232 drivers and five RS232 receivers
Transition region slew rate of 5.5V/μs
5μW low power shutdown mode and TTL three state output
