SP207E Series High Performance RS232 Transceivers

ABSOLUTE MAXIMUM RATINGS

These are stress ratings only and functional

operation of the device at these or any other

above those indicated in the operation sections

of the specifications below is not implied. Exposure

to absolute maximum rating conditions for extended

periods of time may affect reliability.
