The is a +5V powered multichannel RS232 driver/receiver in 16 pin NSOIC package. This ultra low power device is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces. It is particularly suitable for applications where ±12V is not available. The MAX220 has four sections such as dual charge pump DC to DC voltage converters, RS232 drivers, RS232 receivers and receiver/transmitter enable control inputs. The integrated charge pump circuitry eliminates the need for bipolar ±12V supply and enables single supply operation from +5V supply. It is used in interface translation and multidrop RS232 network applications.
