**Total Supply Current at an

external load Capacitance (CL)

and at external timing

capacitance (CX), use the

formula —

IT

—

IT(CL, CX) = [(CL + 0.36CX)VDDf + 2x10–8

RXCX(VDD–2)2f] x 10–3

where: IT in µA (per circuit), CL and CX in pF, RX in megohms,

VDD in Vdc, f in kHz is input frequency.

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

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

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.
