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

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

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

where: f in Hz is the input frequency.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

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

4. The maximum usable resistance RX is a function of the leakage of the capacitor CX, leakage of the MC14538B, and leakage due to board

layout and surface resistance. Susceptibility to externally induced noise signals may occur for RX > 1 MW..

5. If CX > 15 mF, use discharge protection diode per Fig. 11.
