You will need to datawheet at the IC’s datasheet. Here’s the series IC data sheet index Here’s a picture of the chip in a circuit board:. You will find either a circle marking the first pin or a semicircle marking the top of chip.

There are two 4 bit inputs going into the IC. The concept is simple. Parts in this section have a pin count of 14 pins or more. PLA 12 inputs, 32 terms, 6 outputs. The animation below illustrates both of these.

The manufacturer includes other information along with the 74LS00 on the chip. By using this site, you agree to the Terms of Use and Privacy Policy. The lower part numbers were established in the s and s, then higher part numbers were added incrementally over decades. AND-gated positive edge triggered J-K flip-flopasynchronous preset and clear.

List of series integrated circuits – Wikipedia

Floating is not LOW. The device is part of the 74xx family of integrated circuits. Perhaps you thought that with nothing connected the input would naturally go down to 0V. That’s electrical engineering lingo for describing the way the pins are connected to the internal circuitry of the chip. Please clarify your specific problem or add additional details to highlight exactly what you need.


Conversely, the series has “borrowed” from the series – such as the CD and CD being pin-for-pin functional replacements for 74C and 74C N This indicates the package type This will indicate which version of the pinout applies to this chip.

See the How to Ask page for help clarifying this question.

As board designs have migrated away from large amounts of logic chips, so has the need for many of the same gate in one package.

This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations.

If this question can be reworded to fit the rules in the help centerplease edit the question. Note that there are 5 parts to the chip “number”:. See List of series integrated circuits. The following is a list of series digital logic integrated circuits. One way is to connect a pull down resistor from the input to ground. Here is a diagram of the circuit: As you can see, no matter what the input the outputs is always From Wikipedia, the free encyclopedia.

Note that you will have to use pins from two separate banks on the debugger board. If you are looking for an office package, with a word datashet, spreadsheet, etc. In other projects Wikimedia Commons.

June Learn how and when to remove this template message. PLA 12 inputs, 50 terms, 6 outputs. The xx refers to the fact that there are many possible numbers which follow the You’ll use a debugger board for input and output. If you want to use an IC chip, then you will always need to know the pinout. Normally you will just refer to the device by using the two sets of numbers, such asand ignore the letters. Articles lacking in-text citations from June All articles lacking in-text citations.

Some xxx parts, however, do not have a direct counterpart dataseet the standard 74xxx range but deliver new functionality instead, which needs making use of the xxx series’ higher pin count.

Data sheet IC 74xx series

Here is the data sheet of the IC I’m 74xc sure who manufactured the chip but it says N on it: If I change the input bits nothing happens.

You are connecting them to switches so that the inputs are either connected to VCC or left floating. The original series integrated circuits were made by Texas Instruments with the prefix “SN” to create the name SN74xx. Be sure to apply power and ground to both the chip and the debugger board.
