The MAX232 of line drivers/receivers is intended for all communications interfaces, particularly applications where ±12V is not available. The MAX232 uses no external components and is recommended for applications where printed circuit board space is critical. The MAX232 is offered in 26 different packages with temperatures from 0 to +70°C up to -55°C to +125°C.
