Product Summary

The sp239acs is a powered multi-channel RS-232 driver/receiver. The sp239acs provides a variety of configurations to fit most communication needs, especially where ±12V is not available. The sp239acs meets all EIA RS-232D and CCITT V.28 requirements. All, except one model, feature a built-in charge pump voltage converter, allowing the sp239acs to operate from a single +5V power supply. The sp239acs is available in plastic DIP and SOIC packages.
