DESCRIPTION…
The
SP230A
Series are multi–channel 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 DIP and SOIC packages.
