This circuit is from a documentation on the MC1539 from Motorola and may, however, be implemented with equivalent operations. The transistor also supports equivalent.
We found this circuit in an American 1980s documentation, but it can be implemented with modern...
The circuit presented emulates an OR gate with the LM3900, operational transconductance amplifier....
This circuit is the transmitter for the previous project and also for what will come next. It is a...
