2 / 14 page Rev.4/08/02 SP3249E Intelligent +3.0V to +5.5V RS-232 Transceivers © Copyright 2002 Sipex Corporation 2 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 SPECIFICATIONS V CC = +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%), T A = TMIN to TMAX, unless otherwise noted. Typical values are at T A = +25°C.) Note 1: V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V. Input Voltages TxIN ...................................................-0.3V to +6.0V RxIN...................................................................+25V Output Voltages TxOUT.............................................................+13.2V RxOUT,......................................-0.3V to (V CC + 0.3V) Short-Circuit Duration TxOUT.....................................................Continuous Storage Temperature......................-65 °C to +150°C PARAMETER MIN.
