7192 instructor is not teaching us how to understand the pin configurations of the 2 ICs and I’ve been searching around the net but haven’t found anything. This symbol is also similar to figure 5. Indeed, we must read more to understand. You might even need knowledge like this to even pass the interview Ix following user names refer to en. From Wikimedia Commons, the free media repository.

Even if you get a few things wrong it’s likely to come across better and at least show you’ve made an effort. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.
This page was last edited on 6 Juneat Although it will be difficult for you initially; your professor is doing you a favor by forcing you to read the datasheets. As echad said look at the datasheets and have a go at a schematic of a and 74LS connected together. A google search for ” Timer datasheet” once again proves reliable: Post as a guest Name.
This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. In some countries this may not be legally possible; if so: This image was drawn using Adobe Photoshop Elements 3.

This work has been released into the public domain by its author, Swtpc at English Wikipedia. Iv first look at the 74LS; a quick google search will yield the datasheet on the first hit: Swtpc grants anyone the right to use this work for any purposewithout any conditions, unless such conditions are required by law. It appears, that there is a count up mode. He was also on the IEC technical committee. However, since you are probably not accustomed I admit, I’m not ideal at reading them to going through datasheets, I’ll try to guide you through some logic:.
A couple pages down and we find a logic table: I’ve tidied the formatting a bit but one reason homework question often “end badly” is when they don’t jc any attempt to solve it yourself. The following other wikis use this file: The 9 LEDs will blink counting in seconds particularly 9 seconds then it’s going to loop from the beginning 744192 start the counting again.
