SP3243EUEA-L-TR Datasheet, PDF (2/25 Pages) Exar Corporation – 3 Driver/5 Receiver Intelligent +3.0V to +5.5V RS-232 Transceivers

ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation
of the device at these ratings 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 and cause permanent damage to the
device.
V_CC.......................................................-0.3V to +6.0V
V+ (NOTE 1).......................................-0.3V to +7.0V
V- (NOTE 1)........................................+0.3V to -7.0V
V+ + |V-| (NOTE 1)...........................................+13V
I_CC (DC V_CC or GND current).........................+100mA
Input Voltages
TxIN, ONLINE,SHUTDOWN, .....-0.3V to Vcc +6.0V
RxIN...................................................................+15V
Output Voltages
TxOUT.............................................................+13.2V
RxOUT, STATUS.......................-0.3V to (V_CC +0.3V)
