fellas,
do you have any schematic diagram of up down counter using 74ls192 and 7447?
thank you...

We don't mind helping you but we won't do all of the work for you. Please post what you've already done including any ideas you've had and we might be able to make some suggestions. If you've got completely no idea then may be it's your lecuturer's fault and it isn't right that you make him/her look good by cheating and copying from the Internet.hardcore misery said:we need the schematic before wednesday,, i've search through google, can't find anything
See datasheet.where should i connect the Count up Clock input pulse and count down input pulse? and the terminal count down and terminal count up?
.Sir, how can i connect the 74ls192 to the supply? i don't know the configurations... please help me out

Hi Hardcore mysery,
First things first, when you start designing a circuit with TTL or CMOS
logic you've got to make a choice. If you start with TTL you have to
continue with TTL unless you've got good reasons to do otherwise.
The 6 volts supply voltage will do fine for the 4511 but it will be too
much for the 74LS192 which runs only at 5 volts +/- 0.25 volts.
So you'll have to reduce the 6 volts to 5 volts or change the 74LS192
to a 74HC192.
The 4511 was designed to drive common cathode displays, not a common
anode display like the one in your circuit. So you gonna have to replace
the common anode display by a common cathode display and connect
the common cathode to GND, or . . . replace the display driver by a
74XX47 or a 74XX247 or similar.
Now it's up to you, what are you going to do ?
What parts do you already have ?
You can already make some changes to your schematic:
Connect Q0 to D0, Q1 to D1 and so on.
The 10k resistors R8 . . . R11 can be removed from the circuit, I can't
think of any reason to keep them there.
I need to take a pill.
