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 RCA integrated circuit used in this control is uncommon today. The circuit is from an...
We found this active crossover in a Radio Electronics magazine from June 1961. Note the different...
We found this circuit in an old American publication. It can be mounted with TIC106 type SCRs and...
