SN54/74LS is an UP/DOWN MODULO Binary Counter. Separate. Count Up and Count Down Clocks are used and in either counting mode the. 74LS datasheet, 74LS pdf, 74LS data sheet, datasheet, data sheet, pdf, Fairchild Semiconductor, Synchronous 4-Bit Binary Counter with Dual Clock. be preset to either level by entering the desired data at the inputs while the load input is LOW. The output will change independently of the count pulses.

Quote of the day. Apr 14, 7, I hope I’ve described my situation well enough, I just can not figure out why the counter isn’t counting. Try Findchips PRO for pin configuration. I have hseet the data-sheets and read quite a bit on this forum as well, but nothing I try seems to work.

Jan 26, 5. Guaranteed by design, not subject to production testing.

questions about 74193 counter

The de vice can be cleared at any time by the asynchronous reset pin – it may also be loaded in parallel by activating the asyn chronous parallel load pin. The LS outputs can connect directly to the up and down clock inputs of counters such as oror The signals can drive directly the count-up and count-down clocks on the next counter in a series.

Vor bypass capacitor and resistor to ground for the internaldirection o f the external counters.

Often there is a timing diagram that contains the same information along with the critical timing information as well. Connect the encoder quadrature outputs to the A and B inputs. Jan 26, The LFLSS outputs can connect directly to the up and down clock inputs of counters such as or Yes, my password is: We’ll need the schematic you’re useing to help.

A high level applied to this input. Input for external component connection. SiDY Jul data sheet datasheet.

Pin 1 Rbias Input: Pin CLK is the clock signal, RST theloading of the start value is the only feature not inherent in the circuit that is present in the Do you already have an account? Nov 20, 2. This IC is a discontinue item. Jan 26, 9. They all just stay at low, even though I’m giving the counter input a pulse.

InputThe A and B inputs can be swapped to reverse the direction of the external counters. Jan 26, 3.

My best guess is that the pulse is too slow, but even when I apply a Hz square wave nothing happens. Breakthrough in Nanoimprint Lithography Could Revolutionize Flexible Semiconductors Collaborative efforts from UW Madison and partnering Universities have developed a new technique to create low cost, high power flexible semiconductors. Previous shret 2 Jul 17, 22, 1, This was my first experiment with digital logic though, so maybe it daa just make more sense as I work with things.

No external clocks required. Discussion in ‘ The Projects Forum ‘ started by gcentauriJan dheet, I’ve tried many different set-ups but haven’t had any luck. The A and B inputs can be swapped to reverse the direction of the external counters. Rbias X4 or X1 resolution multiplication. Jan 26, 6.

No, create an account now. Jan 26, 7. If not, it’ll always be loading the data inputs into the data outputs. Jan 25, 3 0.
