Notes

1. Rt = 5 kΩ; Ct = 15 pF; for other Rt, Ct combinations and Ct < 0,01 µF see graph Fig.4.

2. Rt = 10 kΩ; Ct = 1000 pF; for other Rt, Ct combinations and Ct > 0,01 µF use formula tWO = K.Rt.Ct.

where: tWO = output pulse width (s)

Rt = external timing resistor (Ω)

Ct = external timing capacitor (F)

K = 0,42 for VDD = 5 V

K = 0,32 for VDD = 10 V

K = 0,30 for VDD = 15 V

3. Tamb = −40 to +85 °C; ∆tWO is referenced to tWO at Tamb = 25 °C.
