We found this circuit in a 1965 Electronic Design. Transistors are still common but admit equivalents for some of them. The circuit drains a current of only 4 mA.
In the figure we show an application in which the 4093 excites a stage with 4 transistors in the...
Circuits and devices can be tested using the tester. The visual indication of the state of the...
This circuit was obtained from Linear Technology documentation from the 80's. Powered by 5 V it...
