Mar 26, 2010 · The 7448 is designed to drive common cathode circuits, while the 7447 is designed to drive common anode circuits. You can use a 4511 and it will drive either depending upon its set up. Like Reply

Jan 23, 2024 · Somehow the 7448 ic outputs are not changing even though the inputs are changing. The inputs are from a jk flipflop counter and im having trouble displaying the output of it in a 7 segment display. It's just stuck to the output 9 or 0. Help.

Oct 23, 2015 · Im working on a traffic light simulation, and we are suddenly tasked to add a 7 segment. We used a 74192 decade counter and I am finding it hard to find the necesary connections for the 74192 to a 7448 or 7447 7 segment decoder. halp pls im toasted

Oct 19, 2007 · im using a 7448 IC coz that is what's available in my case, i've read a spec sheet that says that 7447 is a compliment of 7448. I just got confused on what display to use because i got confused on my schematics putting the 14 segment …

Jul 11, 2012 · The 74LS148 can source 400uA and sink 8mA. (I dont have the datasheet for 7448). That's why the voltage dropped so much when you're sourcing them directly from the outputs. Try inverting the outputs using inverters or inverting buffers to the 7 segment CA LED. It should improve the situations of the 7448. Allen

Feb 8, 2012 · Hello. need your help guys. What are the possible decoders to be used in a cathode 7 segment display? except for 7448. thanks.

Oct 5, 2008 · i need to construct a circuit using 7448 decoder and a 7 segment cathode... the situation goes like this..... \=> if 0,7,4,2,5 is switched on, the 7 segment cathode will display those numbers... otherwise it's off (it won't display anything) but..... if numbers 10,11,12 is switched on, it will display 0(zero) and

Feb 14, 2015 · 74LS47 just a 4 bits BCD to 7-seg decoder, but CD4511 not just a decoder and it has 4 bits latches.
