We show in the figure how to implement the No-AND or NAND logic function using a general-purpose transistor. The 47 k base resistors and collector can be changed to other supply voltages.
The configuration shown was found in an old Poptronics but can be easily assembled using a common...
This circuit is from an old American publication. The indicated transistor is oversized as the 15 V...
Found in a 90’s Radio Electronics magazine, this circuit uses a component from the time, difficult...
