SP3223EEY-L-TR Datasheet, PDF (2/21 Pages) Exar Corporation – 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

Power Dissipation per package
20-pin SSOP (derate 9.25mW/^oC above +70^oC)..750mW
20-pin TSSOP (derate 11.1mW/^oC above +70^oC..900mW
NOTE 1: V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V.
ELECTRICAL CHARACTERISTICS
Unless otherwise noted, the following specifications apply for V_CC = +3.0V to +5.5V with T_AMB = T_MIN to T_MAX.
Typical values apply at V_CC = +3.3V or +5.0V and T_AMB = 25°C (Note 2).
