So you can just move your common lead from VCC to ground and try it. This will help regulator function as desired. The warranty period is 90 days for new, refurbished and repaired parts, and 30 days for used parts, starting on the delivery date of the part.

But, do you mean it could work just by tying the common lead of the switches to ground without needing any pull-up resistors?

Bracket End Fold down Gray. This way it will work for both types of chips. What action do you want to perform? The output still remained on a HIGH state, around 4.

How would you like to proceed?

I repeated 74ls1448 entire process 74le148 another 74LS IC to make sure the first one was working. Ricardo 4, 12 37 So there is no way to drive any of the inputs low. Do you want to continue? If it has 10 switches, then I assume you mean pin, not pin.

That said, when using a chip like the LS you may want to rearrange the connections as shown below and use pullup resistors to establish the high levels on the inputs to the chip. Please enter Email Address. I connected the resistors as shown in the picture below, which should give a HIGH state in the output.

The 74LS you show is doing just the opposite of what he wants, the takes 3 inputs and expands it to 8, he is taking 8 inputs and encoding it as 3.

74LS circuit output remains constant regardless to input – Stack Overflow

Post as a guest Name. I’d still add the pull-ups though. Add to Wish List. In any case, in your example only inputs A, B and C should come from switches. Service Shop has been migrated to a new platform to provide you with a better customer experience.

Thank you for initiating the registration process. To be honest, I didn’t really know how to use the dip switches, but I 774ls148 it now, thanks. You already have a “request for a quote” item in your cart. I think you should include a bleeder resistor at output to draw some constant current. Second, make sure your switches are all off to begin with, and then turn only one on at a time if you do turn on 74,s148 than one, there is a table in the 74LS datasheet which will indicate what the output should be.

I’d could really use a little help. I then tried using pull up resistors, the use and circuit configuration of which is not entirely clear to me, which I think is the problem.
