We show an oscillator that produces rectangular TTL signals based on inverters. Inverters can also be designed with standard NOR or NAND gates. The circuit must be powered by 5 V.
Here we show how to add a reset key to the monostable using two NAND gates (CB127E). When the key...
This short circuit protection circuit accelerates the blown fuse in case of an output overcurrent. The...
This signal injector circuit, an astable multivibrator, was found in a 1971 magazine. The circuit can...
