AI Thread Summary
The discussion revolves around finding a BCD counter IC that supports separate up and down counting clock signals, specifically mentioning the 74LS192, which is currently available. Alternatives like the 74C192, 40192, and 40110 are suggested, though the 40110 does not provide BCD counting. Participants recommend checking local suppliers for stock and considering microcontrollers as a flexible solution for counting functions. The conversation emphasizes the importance of selecting the right IC based on project requirements. Overall, the thread highlights various options and encourages exploring both ICs and microcontrollers for counting applications.

hi,

I wish to design BCD up and down counter circuit for my mini project. I planned to use IC 74LS192. Unfortunately i can't able to get this IC. There is any BCD counter ICs are available with separate up and down counting clock signals. Because i got some ICs for up and down counting which uses only one clock pulse. but i need an IC with two separate clock signals for up and down counting.

Thanks in advance.

The 74LS192 is still current and readily available.

Depends on where you are though.

There are variations on the 192 such as the 74C192, 40192, 74HC192.

If your suppliers have limited stocks, maybe you could find out which counters they have and research those ones.

Another chip that does up-down counting is the 40110.
This does not do BCD counting. It has direct drive for a 7 segment display, so it is easier to use if you want this type of display.
Here is a description of this IC:

and here is a datasheet for it.:

hi vk6kro,

Thanks for your quick reply vk6kro. I will collect the details about the ICs which you have mentioned...:)
 
vrajasekaran,

I don't know what type of project you are doing, but if Up/Down counting is merely a function of the larger project, you may want to consider a uController. A $3 uController and a bit of code can do amazing things. Popular choices include the AVR family and the PIC family.

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
