Some of the manufacturers that make these smaller IC chips are: All chips in this section have three gates, noted by the “3G” in the part numbers. A series TTL device like the one you have has internal pull ups, which means when floating the pins will pull high – basically all your inputs are always high. Note that you will have to use pins from two separate banks on the debugger board. Resources To view pdf documents, you can download Adobe Acrobat Reader.
The original series integrated circuits were made dataheet Texas Instruments with the prefix “SN” to create the name SN74xx. Retrieved from ” https: In other projects Wikimedia Commons.

N This indicates the package type This will indicate which version of the pinout applies to this chip. Notice that this chip has fourteen catasheet. PLA 12 inputs, 32 terms, 6 outputs. If you want to use an IC chip, then you will always need to know the pinout.
Here’s the series IC data sheet index Here’s a picture of the chip in a circuit board:.

When the switch datasheeet OFF it connects nothingand the input is ‘floating’. That’s electrical engineering lingo for describing the way the pins are connected to the internal circuitry of the chip.
One way is to connect a pull down resistor from the input to ground.
Not all functions are available in all families. You don’t need any extra circuitry – the inversion can be built into your head with no electronics required. You will find either a circle marking the first pin or a semicircle marking the top of chip.
Here is a chart to sumarize the behavior of the circuit I built: Please clarify your specific problem or add additional details to highlight exactly what you need.
I’ll write all this up as an answer in a little while, just having dinner. However, different manufacturers will use different prefixes or no prefix at all. If you’re not using all of the pins in one bank, spread them out so it’s datsaheet to tell which is which.
Here’s the series IC data sheet vatasheet Here’s a picture of the chip in a circuit board: The following is a list of series digital logic integrated circuits. All chips in this section have two gates, noted by the “2G” in the part numbers. Retrieved July 27, But without an actual photo that is a guess. AND-gated positive edge triggered J-K flip-flopasynchronous preset and clear. Datxsheet manufacturers continue to make a core subset of this group, but many of these part numbers are considered obsolete and no longer manufactured.

List of books about series integrated circuits. The LS tells you that it is a low power Schottky chip. All chips in the following sections are available 4 to 12 pin surface mount packages. The “x” in the part number is a place holder for the logic family name. Archived PDF from the original on July 9, Also you are not connecting your inputs properly. Here is a chart to sumarize the behavior of the circuit I built:.
