We found this circuit in the 1982 SGS linear integrated circuit manual. The L149 is not common today and the circuit can be implemented with equivalents.
This project was found in a 1982 publication, using only two transistors. Signal injectors are...
The circuit triggers a warning system after the programmed time interval. The circuit uses a CMOS...
We found this circuit in the 1993 Motorola Linear Interface ICs. The operational is unusual today, but...
