All chips in this section have one gate, noted by the “1G” in the part numbers. Also you are not connecting your inputs properly. The xx refers to the fact that there are many possible numbers which follow the The original series integrated circuits were made by Texas Instruments with the prefix “SN” to create the name SN74xx. IC manufacturers continue to make a core subset of this group, but many of these part numbers are considered obsolete and no longer manufactured.

If I change the input bits nothing happens. No, your input bits are never low. N This indicates the package type This will indicate which version of the pinout applies to this chip.

Data sheet IC 74xx series | Elektronika blog. . .

Your switches should connect to GND. Here is a chart to sumarize the behavior of the circuit I built:.

Home Questions Tags Users Unanswered. Just treat the switch being closed as a 0. The manufacturer includes other information along with the 74LS00 on the chip. Older discontinued parts may be available from a limited number of sellers as new old stock NOSthough some are much harder to find. Please clarify your specific problem or add additional details to highlight exactly what you need. For more details, refer primarily to the Texas Instruments documentation mentioned in the References section.


When the switch is OFF it connects nothingand the input is ‘floating’. 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.

From Wikipedia, the free encyclopedia. This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations. If you are looking for an office package, with a word processor, spreadsheet, etc.

Perhaps you thought that with nothing connected the input would naturally go down to 0V.

List of 7400-series integrated circuits

One way is to connect a pull down resistor from the input to ground. Not all functions are available in all families. Parts in this section have a pin count of 14 pins or more.

PLA 12 inputs, 50 terms, 6 outputs. The device is part of datqsheet 74xx family of integrated circuits. If you’re not using all of the pins in one bank, spread them out so it’s easier to tell which is which.

Draw a proper schematic a fritzing diagram of a breadboard is not a schematic and also upload a picture of your circuit. However, different manufacturers will use different prefixes or no prefix at all. 744xx text prefix ; eg. Retrieved from ” https: Surface mount parts with a single gate often in a 5-pin or 6-pin package are prefixed with G instead of The manufacturer provides you with the IC datasheets for all of their products. Conversely, the series has “borrowed” from the series – such as the CD and CD being pin-for-pin functional replacements for 74C and 74C Note that there are 5 parts to the chip “number”: PLA 12 inputs, 32 terms, 6 outputs, 4 state registers.


If you need to update a browser, you might try Firefox which is free open source available for several platforms Since this page uses cascading style sheets for its layout, it will look best with a 7xx which supports the specifications as fully as possible. This is a bank in “control” mode i.

Normally you will just refer to the device by using the two sets of numbers, such asand ignore the letters. Note that there are 5 parts to the chip “number”:.

List of books about series integrated circuits. All chips in this section have two gates, noted by the “2G” in the part numbers. You need to know where the power supply is connected and where the gate inputs and outputs are connected. You don’t need any extra circuitry – the inversion can be built into your head with no electronics required.

The pins on an N-pin DIP are numbered as shown: There are two 4 bit inputs going into the IC. Some of the manufacturers that make these smaller IC chips are: This page was last edited on 27 Novemberat The following is a list of series digital logic integrated circuits.

It’s a good introduction to some of the more complex logic chips that you’ll be using later in the lab. A few alphabetic characters to designate a specific logic subfamily may immediately follow the 74 or 54 in the part number, e.
