APPLICATION INFORMATION
Some examples of applications for the HEF4011UB are shown below.
Because of the fact that this circuit is unbuffered, it is suitable for use in (partly) analogue circuits.

In Fig.9 the oscillation frequency is mainly determined by R1C1,
provided R1

R2 and R2C2
<<
R1C1.
The function of R2 is to minimize the influence of the forward voltage
across the protection diodes on the frequency; C2 is a stray (parasitic)
capacitance. The period T
