I got to do, but something is wrong. The 74LS93 is a binary counter, so it will carry on past 9 74lx90 count up to 15 F in hexadecimal or in binary.

Interface GPS with Arduino. Chris vd Merwe 3 2.

74LS90 IC – Decade Counter IC (7490 IC)

The binary output is 74ps90 to at every tenth pulse and count starts from 0 again. Most Active Software Boards: It will go from and so on. SPI Module of Arduino. But they refer to them as “set-to-nine” inputs It depends on if you must have it roll from 9 to back to 0 on the next count.


If you AND the two 1’s you will get an output when the 10 count occurs – this can be used to reset the counter to Maybe an RC component set on the master reset will help during start up might fix it up Message Edited by kittmaster on Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

There may be other ways to do this ,but this is the simplest method I could find. More time, thank you. Message 2 of Atmospheric Vortex Engine Twister Power.

Post as a guest Name. The bi-quinary code was used in the abacus.

Message 7 of Sorry about my english! The “old” 74xx90 has no defined state after power up. Output 4, BCD Output bit 3. You would have to figure out how to asynchronously reset the ’93 so you don’t get counts 0xA and above.


This enables the cascade connection of the inbuilt counters.


Choosing Battery for Robots. You can also set the simulation option to start all values to zero. I am working with: Latest Blogs Web Browsers: Take a look at the datasheet: Sign up or log in Sign up using Google. The OP can’t get a 74LS Sign up using Email and Password. Please, help with the counter 74LS Message 8 of Bi-quinary is a system for storing decimal digits in a four-bit binary number.

I don’t know what do. The chip can count up to other maximum numbers and return to zero by changing the modes of Please, Anybody helps me?

I am trying to make a simple counter. Most of the 74le90 Looking for a footprint, component, model? By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
