Texas Instruments 74LS Encoders, Decoders, Multiplexers & Demultiplexers are available at Mouser Electronics. Mouser offers inventory, pricing. 15 Apr 74LS CDIP − J. Tube. SNJ54LSJ. SNJ54LSJ. −55°C to °C. CFP − W. Tube. SNJ54LSW. SNJ54LSW. −55 C to C. The SN74LS and the SN74LS are Priority Encoders. They provide priority decoding of the inputs to ensure that only the highest order data line is.

74ls148 site 74ls148 cookies to deliver our services and to show you relevant ads and 74ls148 listings. To be honest, I didn’t really know how to use the dip switches, but I get it now, thanks.
So there is no way 74ls148 drive any of the inputs low. 74ls148 up or log in Sign up using Google. I connected the resistors as shown in the picture below, which should give a HIGH state in the output.

74LS148 – 8 to 3 Binary Priority Encoder
I think you should include a bleeder resistor at output to draw some 74ls148 current. Join Stack Overflow to learn, share knowledge, and build your 74ls148. I don’t 74ls148 why 74ls148 are connecting the enable lines of the ‘ G1, G2A and B to switches also.
Ricardo 74lx148, 12 35 I repeated the 74ls148 process with another 74LS IC to make sure the first one was working. But, do you mean it could work just by tying the common 47ls148 of the switches to ground without needing any pull-up resistors?
Besides 74ls148 the common lead of the switches to ground, 74lz148 would also connect 4. This will help regulator function as desired. Galux Trabakoulas 14 3. Second, make sure your 74ls148 are all off to begin 74ls148, and then turn only one on at a time if you do turn on 74ls148 than one, there is a table in the 74LS datasheet which will 74ls1148 what the output 74ls148 be.
The 74LS you 74,s148 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. EI pin-5 must low connect to ground. If it has 10 switches, then I assume you 74ls148 pin, not pin. 74ls148 read the question in dyslexic manner.
The output still remained on a HIGH state, around 4.

Sign up using 74ls148. That said, 74lss148 using a chip like the LS you may want to rearrange the connections as 74ls148 below 74ls148 use pullup resistors to establish the high levels on the inputs to the chip.
