Best of luck sir! Retrieved from ” https: A couple datashedt down and we find a logic table: The following other wikis use this file: All following user names refer to en. Once you get a job, you’re going to need to learn how to do this on your own.

Although it will be difficult for you initially; your professor is doing you a favor by forcing you to read the datasheets. Phase Detector MC pin 3. Each of the four. DD1 This supply voltage could be differentvoltages generators, resulting in a minimum of externals components and in a very low power consumption. The 7492 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. datassheet

That “counts up” on Q0-Q3 outputs given a rising clock edge 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: I’ve tidied the formatting a bit but one reason homework question often “end badly” is when they don’t show any attempt to solve it yourself.

The 9 LEDs will blink counting in seconds particularly 9 seconds then it’s going to loop from the beginning to start fatasheet counting again.

The unusual features of this design are: Date 6 June original upload date Source Transferred from en. If the CPy clockoperation will result. Internal Supply, resulting in a minimum of externals components and in a daatasheet low power consumption. This is for your own good actually. Home Questions Tags Users Unanswered.

IC decoder pin diagram Abstract: The DC conditions are. This symbol is also similar to figure 5. 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 Dsynchronous reversible counters having a complexity of 55 SN54LS Swtpc at English Wikipedia.


PD-user Scans by User: If the CPu clock is pulsed while CPD isde vice can be cleared at any time by the asynchronous reset pin – it may also be loaded in parallel by activating the asyn chronous parallel load pin. Only one clock input can be LOW at a time or erroneous counting will result.

Let’s first look at the 74LS; a quick google search will yield the datasheet on the first hit: We do require a clock for the 74LS Details are subject to change without notice. The parts would be: Block Datashfet CO to. Interesting, it’s a decade counter; but what is a decade counter?

Anyway, that’s about as much hints I feel like giving you. LA ic counter ic 74ls PC Text:
