Differential voltages are the non-inverting 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 2/12. TL084 - TL084A - TL084B. ELECTRICAL CHARACTERISTICS.
