This transistorized shift register was found in a 1970s RCA documentation. The used transistors can supply 27 V loads with a 3A current of 3 A.
This circuit that drives the load when the logic output is at the low level, was obtained in a...
This full-wave switch has a slightly different configuration than the previous one. We found it in...
In the given circuits, LEDs are used as zeners for the ignition voltage which depends on the...
