SP238A 5V, 4路驱动器/4路接收器RS-232
The SP238a is a multi-channel RS-232 line transceiver that can fit most communication needs, espe- cially where ±12V is not available. It features a built-in charge pump voltage converter, allowing it to operate from a single +5V power supply. All drivers and receivers meet all EIA RS-232D and CCITT V.28 requirements. The SP238A is available in a WSOIC lead free package.
