Your 1k resistor feeding 9V to the circuit makes it much worse. The 9V battery plus must go direct to Vcc on the ‘and to the Potentiometer Vatasheet Started by norbss Yesterday at Started by fastline Yesterday at 8: For a better experience, please enable JavaScript in your browser before proceeding. A real memory chip should be able to store bits when input logic are gone.

cd40147 Input to are tied down to 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. You must log in or register to reply here. Welcome to our site! Your ordinary creates mA supply current spikes because it is powerful and its output switches quickly. Your LEDs light only for a logic low at the outputs and turn off for a logic high.

I have connected 0. The is not a counter, it is just 6 flops with a common clock.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Thread starter neptune Start date Jan 14, I think this maybe because i left inputs open. Also one thing when LED’s are on they flicker with frequencyThough i connected Decoupling capacitor so that it does not happen. The datasheet for the LM dattasheet that two decoupling datashdet bypass capacitors are needed.

I just wanted to store input bits in chip like Is there anything i can do.

Get rid of the useless 1k resistor at the battery. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register. But what shell i do??. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at I also removed 1K resistor.

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.


There are many mistakes: Just for fun i connected Ic’s clock input from Astable mode output. To make it do something useful, you would have to turn it into a shift register or a counter. I am on seven electronics chat forums. Just saying hello Started by MichaelaJoy Yesterday at 6: Each flip-flop stores the logic level at its D-input when the clock goes high. I suppose what kind of IC is this that creates glitch in power supply? If you stop the clock oscillator then each flip-flop will store the logic.

BrownOut Banned Jan 15, Forums New posts Search forums. You still have all the same problems as you had before yourevised the schematic.

Articles Top Dc40174 Search resources. A Cmos should be used because an ordinary causes mA supply current spikes that upset logic ICs, especially when a low current 9V battery is used.

But the problem is any of the output LED’s glow up without even being connected to any Logic 1 or 0. The CD is a 6 bits memory chip.
