Datasheet(PDF) – Fairchild Semiconductor

That is – I wired the circuit to make it count up. I had to switch the wires of the clock and the high between pins 4 and 5 to make it count down. Could you please let me know what way to wire it to automatically count up and then recycle back down.

I need to know what pins to put together. I read your post about cascading them together. However I didn’t really understand what you meant.

I didn’t know what to do with the inputs or whether to take the datwsheet into the inputs of the next chip. Please help me understand.

Roff Well-Known Member Dec 10, I haven’t tested this, but it should work. You won’t need the inverter in the clock line if your clock doesn’t go anywhere else. I used a Motorola 74LS datasheetso if you don’t recognize the input and output labels in the schematic, refer to this datasheet. Develop a digital display clock circuit based on the timer using the counter chip 74LS The circuit has a single digit output a signly 7 segment display that counts from 0 to 9 seconds.


The circuit overflows from 9 back to 0 and continually repeast the count. You must log in or register to reply here.
