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.
VCC.......................................................-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
ICC (DC VCC or GND current).........................+100mA
Input Voltages
TxIN, SHUTDOWN .........................-0.3V to VL+0.3V
RxIN...................................................................+25V
Output Voltages
TxOUT.............................................................+13.2V
RxOUT, .......................................-0.3V to (VL + 0.3V)
Short-Circuit Duration
TxOUT......................................................Continuous
Storage Temperature.......................-65°C to +150°C
Power Dissipation per package
20-pin TSSOP (derate 7.0mW/oC above +70oC..560mW
NOTE 1: V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V.
ELECTRICAL CHARACTERISTICS
VCC = VL = +3.0V to +5.5V, C1 - C4 = 0.1µF, tested at +3.3V +/-10%, C1 = 0.047µF, C2 - C4 = 0.33µF, tested at
+5.0V +/-10%, TAMB = TMIN to TMAX, unless otherwise noted. Typical values are at Vcc = VL = 3.3V, TA = +25ºC.
