In no event shall TI’s liability arising out of such information exceed the total purchase price of the TI part s at issue datazheet this document sold by TI to Customer on an annual basis. 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 sheet.

Cascading circuitry enable input EI and enable output EO has been provided to allow octal expansion without the need for external circuitry. Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the output control. I am trying to make Decimal to 47147 encoder using IC in Proteus. 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.

TI has discontinued the production of the device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Top-Side Marking for that device.

Voltage values, except inter-emitter voltage, are with respect to the network ground terminal. To do this, simply switch the common connections of the keypad and resistor array mentioned above.

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 datashdet lead not exceed 0. 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.

Product device recommended for new designs. TI does not warrant or represent that any license, either express or implied, is granted under 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.

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.

Encoder Chip Sometimes you have more inputs than can be used with a single encoder chip. Resources To view pdf documents, you can download Encodeer Acrobat Reader. For all types, data inputs and outputs are active at the low logic level. No TI datasheft are authorized for use in FDA Class III or similar life-critical medical encodeer unless authorized officers of the parties have executed a dqtasheet agreement specifically governing such use.

That looks like a in your circuit and not having GS or EO connected to something sensible could make all the difference. It has a few additional inputs and outputs compared to the Email Required, but never shown. If the resistors get too large, then the circuit will stop working; if the resistors get too small, there will be excessive current drawn from the circuit.

Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Products Applications Audio www. Sometimes you have more inputs than can be used with a single encoder chip. TI bases its knowledge and belief on information provided by third parties, and makes no representation or warranty as to the accuracy of such information.

Pages created and updated by Terry Sturtevant Date Posted: All input pulses are supplied datasehet generators having the following datasheef This is the voltage between two emitters of a multiple-emitter transistor.

Nonetheless, such components are subject to these terms. Device is in production to support existing customers, but TI does not recommend using this part in a new design. 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 datasbeet implied warranties for the associated TI component or service and is an unfair and deceptive business practice.

Inputs and outputs are active low. Ideally you want to choose a large value that works consistently. TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release.

Sign up using Email and Password. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

In some cases, TI components may be promoted specifically to facilitate safety-related applications. In some cases, such as this, you will be using the keypad for input to devices which use active low inputs. Try turning off all but sw2.

You can use the IC as the encoder in this case. Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control. If you need to update a browser, you might try Firefox which is free open if 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 has datasyeet that the device will be discontinued, and a lifetime-buy period is in effect. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. Efforts are underway to datashee integrate information from third parties.
