APPLICATION INFORMATION
Some examples of applications for the HEF4093B are:
If a Schmitt trigger is driven via a high impedance (R > 1 k ) then it is necessary to incorporate a capacitor C of such
value that:
C
Note
The two inputs may be connected together, but this will result in a larger through-current at the moment of switching.
