4 TL74 ABSOLUTE MAXIMUM RATINGS (Ta= C) PARAMETER SYMBOL RATING UNIT Supply Voltage (Note 1) V CC ±18 V Input Voltage (Note 2) V IN ±1 V Differential Input Voltage (Note 3) V I(DIFF) ±3 V Power Dissipation P D 68 mw Output ShortCircuit Duration (Note 4) Infinite Operating Temperature T OPR ~ 7 C Storage Temperature T STG ~ 1 C Notes: 1. All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the supply voltages where the zero reference level is the midpoint between Vcc and Vcc. 2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 1 volts, whichever is less. 3. Differential voltages are at the noninverting input terminal with respect to the inverting input terminal. 4. The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded.. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied.
