As echad said look at the datasheets and have a go at a schematic of a and 74LS connected together. LA ic counter ic 74ls PC 71492 A google search for ” Timer datasheet” once again proves reliable: A number of resistors if need be A single or more capacitor if need be.
It appears, that there is a count up mode. Common AFreceiver is a DC-coupled design, as shown above. The 9 LEDs will blink counting in seconds particularly 9 seconds then it’s going to loop from the beginning to start the counting again.
We do require a clock for the 74LS I’ve tidied the formatting a bit but one reason homework question often datashest badly” is when they don’t show any attempt to solve it yourself.

This image was drawn using Adobe Photoshop Elements 3. 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:.
PD-user Scans by User: The timestamp is only as accurate as the datasheett in the camera, and it may be completely wrong. Interesting, it’s a decade counter; but what is a decade counter? 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.

Anyway, that’s about as much hints I feel like giving you. Block Diagram CO to.
The 4K7 and R resistors set the gain of the amplifier which in this case, is set to 48, giving an overall voltage gain of over A unit cell consists of 4 pairs o f transistors where each pair is made up of a 71492drain driver. Retrieved from ” https: Email Required, but never shown. DD1 This supply voltage could be differentvoltages generators, resulting in a minimum of externals components and in a very low power consumption.
Although it will be difficult for you initially; your professor is doing you a favor by forcing you to read the datasheets. No abstract text available Text: A couple pages down and we find a logic table: Sign up or log in Sign up using Google. The unusual features of this design are: The parts would be: Well it sure seems as though this chip is pretty useful!

He was also on the IEC technical committee. Volume 1 contained a tutorial on how to read and create these symbols. Swtpc at English Wikipedia. This symbol is also similar to figure 5.
