Since you already need one section of aand there are 6 gates per IC, you simply go. Finally, you should not count on TTL outputs driving high, as you have shown. For a circuit board with a ground plane, the usual guideline is at least one cap per 5 ICs.

Okay I wired 7,9, and 10 together and then connected them to a 1K resistor to 5V. I’m still getting the same effect.

Without this buffering, your switch should not work on a button push, only on a release. Home Questions Tags Users Unanswered. It’s always the simple things.

As further issues arise I see myself stuck once more with a dysfunctional circuit.

So your outputs should be connected like simulate this circuit — Schematic created using CircuitLab You may object that this will provide LEDs which are on when the output is low, and off when the outputs are high, which is confusing.

You may object that this will provide LEDs which are on when the output is low, and off when the outputs are high, which is confusing. Oh, Ill change that and see shwet happens.

You can often get away with less, but as you’ve just learned, insufficient decoupling can have weird symptoms.

WhatRoughBeast 49k 2 28 I’d reduce that down to something in the nF to 1uF range. I added a 0. I switched the LEDs around and connected their input to 5V and their ground to the output pins. Whenever I press the clock button I get all of the leds on except 7461 one or two, with some flashing during the button press. That’s probably causing as much trouble as no debounce was.

So your outputs should be connected like. For breadboards, use a cap for each IC. Then I used a pullup resistor for the clear switch. TTL works much better pulling loads down. Sign up using Facebook.
