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, ONLINE,

SHUTDOWN, .....................................-0.3V to +6.0V

RxIN...................................................................+25V

Output Voltages

TxOUT.............................................................+13.2V

RxOUT, STATUS.......................-0.3V to (VCC + 0.3V)

Short-Circuit Duration

TxOUT.....................................................Continuous

Storage Temperature......................-65°C to +150°C

Power Dissipation per package

28-pin SSOP

(derate 11.2mW/oC above +70oC).................900mW

28-pin TSSOP

(derate 13.2mW/oC above +70oC)...............1100mW

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

ELECTRICAL CHARACTERISTICS

VCC = +3.0 to +5.5, C1 -C4 = 0.1µF (tested at 3.3V + 5%), C1-C4 = 0.22µF (tested at 3.3V + 10%), C1 = 0.047µF, and C2-C4 = 0.33µF (tested at 5.0V

+ 10%), TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
