2. Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.
3. The formulas given are for the typical characteristics only at 25_C.
4. To calculate total supply current at loads other than 50 pF: IT(CL) = IT(50 pF) + (CL – 50) Vfk where: IT is in mA (per package), CL in pF,
V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.003.
