This circuit was found in a Motorola documentation from 1975. Modern equivalent transistors such as the BF245 can be used. The circuit is powered by 9 V voltage from cells or batteries.
This circuit is from an American cookbook from 1977. The circuit generates a voltage of...
In the figure we have the simple way to implement the NO-OR or NOR function with common diodes and a...
We found this configuration in an integrated circuits manual. The transistor, which can be of any...
