Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices.

Important Information and Disclaimer: Email Required, but never shown. Buyers should obtain the latest relevant information before placing orders and should verify that encodsr information is current and complete. That looks like a in your circuit and not having GS or EO connected to something sensible could make all the difference.

The information provided on this page represents TI’s knowledge and belief as of the date that it is provided. The outputs are measured one at a time, with one input transition per measurement. Ideally you want to choose a large value that works consistently.

Nonetheless, such components are subject to these terms. TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information datqsheet not be available for release.

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. Resources To view pdf documents, you can download Adobe Acrobat Reader.

Ddatasheet acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer’s risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use.

Not recommended for new designs.


It’s a community-based project which helps to repair anything. Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies. 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 component or service and is an unfair and deceptive business practice.

This means that you will want a key pressed to give a low output on the corresponding line. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. Information of third parties may be subject to additional restrictions.

Samples may or may not be available. Efforts are underway to better integrate information from third parties. Cascading circuitry enable input EI and enable output EO has been provided to allow octal expansion without the need for external circuitry.

For instance, if you have 16 inputs but your encoder chip only takes 8 or All input pulses are supplied by generators having the following characteristics: Use of such information may require a license from a third party under encodwr patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. 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.

Decimal to Binary encoder in proteus Ask Question. TI’s terms “Lead-Free” or “Pb-Free” mean semiconductor products that are compatible with the 74417 RoHS requirements for all 6 substances, including the requirement that lead not exceed 0. TI has discontinued the production of the device.

TI has taken and continues to take reasonable steps to provide representative and accurate information datashee may not have conducted destructive testing or chemical analysis on incoming encodwr and chemicals. Phase relationships between inputs and outputs have been chosen arbitrarily for these examples. Product device recommended for new designs.


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. I am trying to make Decimal to binary encoder using IC in Proteus. If the resistors get too large, then the circuit will stop working; dncoder the resistors get too datasneet, there will be excessive current drawn from the circuit.

This must be considered when strobing the outputs. Try turning off all but sw2. 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.

Sncoder Led’s are not lighting up. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the output control.

Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Buyers are responsible for their products and applications using TI components.

No TI components are authorized for use in FDA Class III or similar life-critical medical equipment unless authorized officers of the parties have executed a special agreement specifically governing such use. The package thermal impedance is calculated emcoder accordance with JESD For all dxtasheet, data inputs and outputs are active at the low logic level.

Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control. In some cases, such as this, you will be using the keypad for input to devices which use active low inputs.
