2 / 20 page SP3238EDS/04 SP3238E +3.0V to +5.5V RS-232 Transceivers © Copyright 1999 Sipex Corporation 2 NOTE 1: V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 15V. 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, EN ...............................-0.3V to +6.0V RxIN...................................................................+15V Output Voltages TxOUT...............................................................+15V RxOUT, STATUS.......................-0.3V to (V CC + 0.3V) Short-Circuit Duration TxOUT.....................................................Continuous Storage Temperature......................-65 °C to +150°C Unless otherwise noted, the following specifications apply for V CC = +3.0V to +5.5V with TAMB = TMIN to TMAX. Typical values apply at V CC = +3.3V or +5.0V and TAMB = 25°C.
