Datasheet(PDF) – STMicroelectronics
VDD1 must be, resulting in a minimum of externals components and in a very low power consumption. 7412 Supply, resulting in a minimum of externals components and in a very low power consumption.
Block Diagram CO to. 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.
So we have some knowledge about that chip; what about the timer? Even if you get a few things wrong it’s likely to come across better and at least show you’ve made an effort. Try Findchips PRO for pin diagram of ic PeterJ 16k 20 42 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.
Interesting, it’s a decade counter; but what is a decade counter?

Only one clock input can be LOW at a time or erroneous counting will result. Well it sure seems as though this chip is pretty useful! In some countries this may not be legally possible; if so: If the CPy clockoperation will result. A unit cell consists of 4 pairs o f transistors where each pair is made up of a PMOSdrain driver. PD-user Scans by User: Nick Williams 1, 3 11 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 unusual features of this design are: As echad said look at the datasheets and have a go at a schematic of a and 74LS connected together.
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: Let’s first look at the 74LS; a quick google search will yield the datasheet on the first hit: A google search for ” Timer datasheet” once again proves reliable: Swtpc grants anyone the right to use this work for any purposewithout any conditions, unless such conditions are required by law.
