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 VCC or GND current).........................+100mA Input Voltages TxIN, ONLINE, SHUTDOWN, ....-0.3V to Vcc + 0.3V RxIN...................................................................+25V Output Voltages TxOUT.............................................................+13.2V RxOUT, STATUS.......................-0.3V to (V CC +0.3V) Short-Circuit Duration TxOUT....................................................Continuous Storage Temperature......................-65°C to +150°C V CC = +3.0V to +5.5V, 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%), T AMB = TMIN to TMAX, unless otherwise noted.
