AI Thread Summary
The discussion centers around selecting an appropriate integrated circuit (IC) for counting signals from an encoder, specifically addressing the use of the 74LS47, which is not suitable for this application. Participants clarify that the user likely has a quadrature encoder that requires counting in both directions. They inquire about the bit requirements for counting and the design logic needed to process the encoder's two output signals. Recommendations include looking for counter ICs that support up/down counting functionality. Understanding these components and their interactions is essential for successfully implementing an encoder counter circuit.

i am want to make circuit that use an encoder counters..
but i don't know which ic can counter for encoder??
i am using 74LS47 for encoder counters?but, it didn't work??
is 74LS47 can use for counter encoders??
which IC can used for encoder counters??
thanks anyway

What exactly is an 'encoder counter?'

- Warren
 
My guess would be that he has a quadrature encoder output, and wants to count up for rotation in one direction, and count down for rotation in the other direction. Is that correct, novrisa?

How many bits of counting do you need? Do you know how to design the logic to take the quadrature encoder outputs (two signals, correct?), and use those to make an up/down signal and a counter clock signal? Then, do you know of counter ICs that have an up/down count control input?
