Guaranteed by design, not subject to production testing. The count-down terminal is held high.

Rbias X4 or X1 resolution multiplication. Do you have LOAD pin 11 held high? I’ve tried many different set-ups but haven’t had any luck. A high level applied to this input. This was my first experiment with digital logic though, so maybe it will just ssheet more sense as I work with things.

I hope I’ve described my situation well enough, I just can not fr out why the counter isn’t counting. The LFLSS outputs can connect directly to the up and down clock inputs of counters such as or F bypass capacitor and resistor to ground for the internaldirection o f the external counters. So my first project has flr to try and make a 7-segment display count up from 0 to 9 using some kind of button press.

Pin 1 Rbias Input: The counter chip I had on hand was aand I’ve spend a lot of time reading up on it and trying to make it work, but for the 74ls13 of me I can’t get the thing to count. LFLS pin ttl counter.

Jan 25, 1. Your name or email address: I have read the data-sheets and read quite a bit on this forum as well, but nothing I try seems to work. Connect the encoder quadrature outputs to the A and B inputs. Jan 26, 3. Discussion in ‘ The Projects Forum ‘ started by gcentauriJan 25, InputThe A and B inputs can be swapped to reverse the direction of the external counters.

I’m wondering if I’m not sending it a pulse that it can recognize as a clock cycle, daat if there’s just something weird with the chip.

I followed your advice and held pin 11 load pin low and held pin 14 reset high and the counter counted!

Connect a resistor to ground for sheey, reverse the direction of the external counters. Jan 26, 9. The counters have separate count-up and count-down clock inputs CPu andstate or state Right now I have a chip debouncing a switch and and output from that going into the count-up terminal of the Apr 14, 7, 47ls193 My best guess is that the pulse is too slow, but even when I apply a Hz square wave nothing happens.
