IT = (3.5 x 10–2) RXCXf + 4CXf + 1 x 10–5 CLf

IT = (8.0 x 10–2) RXCXf + 9CXf + 2 x 10–5 CLf

IT = (1.25 x 10–1) RXCXf + 12CXf + 3 x 10–5 CLf

where: IT in µA (one monostable switching only),

where: CX in µF, CL in pF, RX in k ohms, and

where: f in Hz is the 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.
