Decoder ; Supply 74hcc74 Production processing does not necessarily include testing of all parameters. The ‘sensitive gate’ E and ER series are intended for interfacing with low power drivers, including microcontrollers.

The circuit below works in simulation: But I tried several times with breadboard from scracth and have the following problem: My guess would be you mixed up some pins, or used something that is not a capacitor. I made this on breadboard three times from scratch I couldnt find any wrong connection yet.
