This circuit can modulate a laser rate at frequencies of 50 kHz. We found the old documentation. The bipolar transistors can be the BD135 and 136 and the FET admits equivalent.
The purpose of this interesting circuit found in a 1977 documentation is to complete the last...
This circuit allows to drive a triac with high power AC load from a CMOS output or directly from a...
This circuit was obtained in a documentation from the 80's. However, using TTL it is still modern,...
