hey brian, i think i got a clear view. am using cd4543 now. first i gave 5 v supply and 150 ohms as ma limiting resistors but the current passed was only 3 mA. hence now i'm going to give 5v supply and place 1 k ohm resistor,so tat i get 9-12 ma current which can easily drive ma ic. will this...
brian how to measure current output of the ic once the supply is given to ic?

audioguru thanks soo much. i'll be really thankful,if yu can answer my silly doubts.actually we 've to use current limittin resistors. here i've lot of confusion .as yu said i took the...
brian i made up my mind to use cd4543 and am planning to use the current limitting resistors but in the datasheet i found a pin named latch disable???should i ve to keep that high or low??
can you guide me of how should i start with datashet? brian i'm very new to this kinda work.i've the habit of doing only codes.so far i've not assigned any designs on the board on my own.if i 've the schematic,i mount it else i dono wat current requirement i need and how much volage i should...
k thanks brian,first i taut of using optocouplers but now i made up ma mind to do this using decoder and uln2003. even if i use decoder limiting resistors are required ????if so wat is the range of resistor i can use??
no i 've to use all these and work on it. by d way if you are online can you clarify my doubt imiedietly??i need a response from you now so that i can proceed my question.
betwixt,its amazing to read your explanations.i'm also a person who is looking for the same thing wat irshad is doing except the controller because am not yet clear wat setup am asked for.
i would be really thankful if you could suggest based on the below articles which i'm bought to make a led...

fine for example if i ve few IC's in my hand relevent to some function / application say for example :LED display.
as a starter how should i diagonise this??? this is my question. you may doubt that cant i do if am given a schematic but am talking abt the extreme .as a fresher how wud i start to...
fine pranam,am completely clear with ur ideas.
now can yu tell me how to go through the data sheets generally.i.e if i use so and so Ic, i can match with other so ans so IC. how should i start as a fresher??
uln with lcd
pranam do we require any limiting resistors for each segment of the led to burn in case if we use uln???

ok FvM,please suggest me one bcd to 7 seg decoder and am pretty confused wether to use limiting resistors or not.
because if am going to use one...
