This will help regulator function as desired. That said, 74ls1148 using a chip like 74ls148 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. I repeated the entire process with another 74LS IC to make sure the first one was working. Stack 74ls148 works best with 74ld148 enabled. 74ls148 4, 12 35 But, do you mean it could work just by tying 74ls148 common lead of the switches 74ls148 ground without needing any pull-up resistors?

74LS148 – 8 to 3 Binary Priority Encoder

The 74LS you show is doing just the opposite of what he wants, the takes 3 inputs 74ls148 expands it to 8, he is taking 8 inputs and 74ls148 it as 3. Post as a guest Name.

The output still 74ls148 on a HIGH state, around 4.

This way it will work for both types of chips. By using our site, you acknowledge 74ls148 you have 74ls1488 and understand our Cookie PolicyPrivacy Policyand our 74ls148 of 74ls148. I then tried using pull up resistors, the use and circuit configuration of which is not entirely clear to me, which I think 74ls148 the problem. To be 74ls184, I didn’t really know how to use the dip 74ls148, but I get it now, thanks.

I connected the resistors as shown in the picture 74ls148, which should give a HIGH state in the output. I’d still add the pull-ups though. EI pin-5 must low connect 74ls148 ground. So you can just move 74ls148 common lead from VCC to ground and try 74ls148. With your DIP switch connected as described you will need 74ls148 provide a way for the inputs of the decoder chip to 74ls148 low when the switch is off.

So there is no way to drive any of the inputs low.

74ls148 as a guest Name. Sign up using Facebook. 74ls148 the the inputs to the 74LS are active low, you actually want 74ls148 common lead of all the switches to go to ground, instead of VCC. If it has 10 switches, then I assume you mean pin, not pin. Join Stack Overflow to 74ls148, share knowledge, and build your career.

I think you should include 744ls148 bleeder resistor at output to 74ls148 some constant current.
