To calculate total supply current at loads other than 50 pf: IT() = IT(50 pf) + ( 50) Vfk where: IT is in µa (per package), in pf, V = ( ) in volts, f in khz is input frequency, and k = µadc µadc This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range (Vin or Vout). Unused inputs must always be tied to an appropriate logic voltage level (e.g., either or ). Unused outputs must be left open. 2 OTOROLA COS LOIC DATA
