Email Required, but encode shown. Note that while the inputs are active lowthe outputs are active high. Encoder Chip Sometimes you have more inputs than can be used with a single encoder chip. This component has a RoHS exemption for either 1 lead-based flip-chip solder bumps used between the die and package, or 2 lead-based die adhesive used between the die and leadframe.

Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

Buyers are responsible for their products and applications using TI components.

Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or enckder thereof.

In no event shall TI’s liability arising out of such information exceed the total purchase price of the TI part s at issue in this document sold by TI to Customer on an annual basis. TI does not warrant or represent that any license, either express or implied, is granted dwtasheet any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used.

The outputs are measured one at a time, with one input transition per measurement. Buyer will fully indemnify TI and its representatives against any damages arising out of the use datashert any TI components in safety-critical applications.


I am trying to make Decimal to binary encoder using IC in Proteus. This is the voltage between two emitters of a multiple-emitter transistor. 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 browser which supports the specifications as fully as possible.

TI is not responsible or liable for such altered documentation. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. Jasen 9, 14 Information of third parties may be subject to additional restrictions.

In that case, you want to cascade the encoder chips so that instead of having two sets of three bit outputs, you have a single four bit output. Inputs and outputs are active low. Not recommended for new designs.

The package thermal impedance is calculated in accordance with JESD Decimal to Binary encoder in proteus Ask Question. Make sure power is connected too.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data encover. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI.

The LEDs may be connected backwards, plus 7447 one needs a ballast resistor.

Below is the schematic for how to cascade two s to give a single 4 bit output. Resources To view pdf documents, you can download Adobe Acrobat Reader.

That looks like a in your circuit and not having GS or EO connected to something sensible could make all the difference. Pages created and updated by Terry Sturtevant Date Posted: Nonetheless, such components are subject to these terms. Post as a guest Name. If you are looking for an office package, with a word processor, spreadsheet, etc.


TI has discontinued the production of the device. It’s a community-based project which helps to repair anything. Try turning off all but sw2. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI datzsheet or service and is an unfair and deceptive business practice.

Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control. TI is not responsible or liable for any such statements. For instance, if you have 16 inputs but your encoder chip only takes 8 or Ricardo 4, 14 37 But Led’s are not lighting up.

Home Questions Tags Users Unanswered. What am I doing wrong? Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI has taken and continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical dstasheet on incoming materials and chemicals.

No TI components are authorized for use in FDA Class III or similar life-critical medical ecnoder unless authorized officers of the parties have executed a special agreement specifically governing such use. Encodef all types, data inputs and outputs are active at the low logic level. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty.

You can use the IC as the encoder in this case. This must be considered when strobing the outputs.

Active low inputs In some cases, such as this, you will be using the keypad for input to devices which use active low inputs.
