MAX225EWI+G36 Datasheet PDF - Maxim Integrated

The MAX225EWI+G36 is a +5V powered multichannel RS232 driver/receiver in 28 pin WSOIC package. This 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 MAX225 has four sections such as dual charge pump DC to DC voltage converter, RS232 driver, RS232 receiver 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. The device uses no external components and is recommended for applications where printed circuit board space is critical. It is used in interface translation and multidrop RS232 network applications.
