This is for your own good actually.

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.

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?

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.
