Efforts are underway to better integrate information from third parties. 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.

Home Questions Tags Users Unanswered. Active low inputs In some cases, such as this, you will be using the keypad for input to devices which use active low inputs. Ricardo 4, 14 37 In some cases, TI components may be promoted specifically to facilitate safety-related applications.

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. Note that while the inputs are active lowthe outputs are active high.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. The information provided on this page represents TI’s knowledge and belief as of the date that it is provided.

PC/CP Cascading Encoders

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 in accordance with JESD TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers dataheet other limited information may not be available for release.


Try turning off all but sw2.

Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. Cascading circuitry enable input EI and enable output EO has been provided to allow octal expansion without the need for external circuitry.

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related enoder concerning its products, dataasheet any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI.

TI has discontinued the production of the device. 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. That looks like a in your circuit and not having GS or EO connected to something sensible could make all the difference.

The outputs are measured one at a time, with one input transition per measurement.

Encoder Lab

Voltage values, except inter-emitter voltage, are with respect to the network ground terminal. Some of these extra pins are what allow these devices to be cascaded. Sign up using Facebook.

TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at 7447 Buyer’s risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. Jasen 9, 14 Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

It’s a community-based project which helps to repair anything. This must be considered when strobing the outputs. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. If you are looking for an office package, with a word processor, spreadsheet, etc.

To do this, simply switch the common connections of the keypad and resistor array mentioned above. TI is not responsible or liable for such altered documentation. Below is the schematic for how to cascade two s encooder give a single 4 bit output.


74LS147 – 74LS147 10 to 4 Priority Encoder Datasheet

Product device recommended for new designs. TI’s terms “Lead-Free” or “Pb-Free” mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0. For all types, data inputs and outputs are active at the low logic level. 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.

Email Required, but never shown. This is the voltage between two emitters of a multiple-emitter transistor. Buyer represents and agrees that it has all the necessary expertise to create and enxoder 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.

For envoder, if you have 16 inputs but your encoder chip only takes 8 or 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. Nonetheless, such components are ix to these terms. What am I doing wrong? I am trying to make Decimal to binary encoder using IC in Proteus. Sign up using Email and Password. All input pulses are supplied by generators having the following characteristics: Resources To view pdf documents, you can download Adobe Acrobat Reader.

TI has taken and continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals.
