#Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.

**āThe formulas given are for the typical characteristics only at 25_C.

†To calculate total supply current at loads other than 50 pF:

IT(CL) = IT(50 pF) + (CL – 50) Vfk

where: IT is in µA (per package), CL in pF, V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.008.

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 VSS ≤ (Vin or Vout) ≤ VDD.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must

be left open.
