But the problem is any of the output LED’s glow up without even being connected to any Logic 1 or 0. LED’s light up and down randomly without sequence. I think this maybe because i left inputs open.
But what shell cd401174 do??. Also one thing when LED’s are on they flicker with frequencyThough i connected Datasheeet capacitor so that it does not happen. There are many mistakes: The 9V battery plus must go direct to Vcc on the ‘and to the The battery minus must go to Vss on the ‘ and to GND on the The is not a counter, it is just 6 flops with a common clock.
CD (TI) – Cmos Hex D-type Flip-flop
To make it do something useful, you would have to turn it into a shift register or a counter. Even if you turn it into a counter, the oscillating frequency of the must be less than 20Hz, or all LEDs will seem to light dimly.
Each LED must have its own current limiting resistor. A Cmos should be used because an ordinary causes mA supply current spikes that upset logic ICs, especially when a low current 9V cd40714 is used.

BrownOut Banned Jan 15, You still have all the same problems as you had before yourevised the schematic. AllVol New Member Jan 15, The datasheet for the LM shows that two decoupling supply bypass capacitors are needed. Get rid of the useless 1k resistor at the battery. When the tries to conduct mA then the supply voltage to datzsheet drops to zero.
40174 ic with 555 as clock funny behaviour.
I have connected 0. Input to are tied down to high. But still LED’s are flickering. I suppose what kind of IC is this that creates glitch in power supply? Your ordinary creates mA supply current spikes because it is powerful and its output switches quickly.
Your 1k resistor feeding 9V to the circuit makes it much worse. I am not making sequencer. I also removed 1K resistor. I just wanted to store input bits in chip like cd440174 But I think whats the use when its input needs fix logic to either high or low. A real memory chip should be able to store bits when input logic are gone. Is there anything i can do. Dataaheet CD is a 6 bits memory chip.
Each flip-flop stores the logic level at its D-input when the clock goes high. But your is a clock oscillator so if the D-input changes then the output of the flip-flop also changes each time the goes high. If you stop the clock oscillator then each flip-flop will store the logic. Your LEDs light only for a logic low at the outputs and turn off for a logic high.
