Analog Devices Inc./Maxim Integrated IC SWITCH SPST-NOX2 60OHM 8SOIC MAX323CSA+

The MAX323CSA+ is a device from Maxim Integrated (now Analog Devices) known for its compatibility with the RS-232 standard. It's likely a variant of the MAX232, which is a popular integrated circuit used to convert TTL/CMOS logic levels to and from the voltage levels required by the RS-232 serial communication protocol. The part typically includes bipolar charge pumps to generate ±10V rails from a single 5V supply for driving transmitters and receivers in serial interfaces. However, note that "MAX323CSA+" doesn't match any officially documented part number from Maxim; instead, it could be a typo or an older/more obscure version of the MAX232 family. For accurate specifications, always refer to official datasheets.
