APPLICATION INFORMATION
Some examples of applications for the HEF4069UB are shown below.
In Fig.7 an astable relaxation oscillator is given. The oscillation frequency is mainly determined by R1C1, provided
R1 << R2 and R2C2 << R1C1.
Fig.7
(a) Astable relaxation oscillator using two HEF4069UB inverters; the diodes may be BAW62; C2 is a
parasitic capacitance. (b) Waveforms at the points marked A, B, C and D in the circuit diagram.
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

is given by T

, in which
V
is the signal threshold level of the inverter. The period is fairly independent
of V
