DESCRIPTION

The HEF4069UB is a general purpose hex inverter. Each

of the six inverters is a single stage.

HEF4069UBP(N): 14-lead DIL; plastic

(SOT27-1)

HEF4069UBD(F): 14-lead DIL; ceramic (cerdip)

(SOT73)

HEF4069UBT(D): 14-lead SO; plastic

(SOT108-1)

( ): Package Designator North America

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.

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 Tp is given by Tp = T1 + T2, in which

VST is the signal threshold level of the inverter. The period is fairly independent

of VDD, VST and temperature. The duty factor, however, is influenced by VST.
