The SP230A Series are multichannel RS-232 line drivers/receivers that provide a variety of configurations to fit most communication needs, especially where 12V is not available. Some models feature a shutdown mode to conserve power in battery-powered systems. Some require no external components. All, except one model, feature a built-in charge pump voltage converter, allowing them to operate from a single +5V power supply. All drivers and receivers meet all EIA RS-232D and CCITT V.28 requirements. The Series is available in plastic and ceramic DIP and SOIC packages.
