The TAA865 integrated circuit used in this 1986 project is no longer common today. The circuit is a documentation of the time and the time is given by RC that has indicated the maximum values.
We found this circuit in a publication from the 1980s. It can function as a touch switch and if...
The figure shows how to implement an inverter trigger using the LM3900. The LM3900 is a NORTON...
In this circuit we have the way to obtain a pseudo sequential effect of LEDs using 3 FETs. The...
