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 current)...........................................+100mA

Input Voltages

TxIN, SHUTDOWN = GND.........................-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 Packages

20-Pin TSSOP

(derate 7.0mW/°C above+70°C)............................560mW

NOTE 1: V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V.

ELECTRICAL CHARACTERISTICS

(VCC = VL = +3V to +5.5V, C1-C4 = 0.1µF, tested at +3.3V +10%, C1 = 0.047µF, C2-C4 = 0.33µF, tested at +5.0V +10%, TA = TMIN to TMAX, unless

otherwise noted. Typical values are at VCC = VL +3.3V, TA = +25°C.)
