Product Summary

The SP235ACP is a multi–channel RS-232 line driver/receiver that provides 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. The SP235ACP meets all EIA RS-232D and CCITT V.28 requirements. The Series is available in plastic DIP and SOIC packages.
