Encoder Chip Sometimes you have more inputs than can be used with a single encoder chip. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. Home Questions Tags Users Unanswered. 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.

Nonetheless, such components are subject to these terms. This means that you will want a key pressed to give a low output on the corresponding line. Information of third parties may be subject to additional restrictions. Jasen 9, 14 Cascading circuitry enable input EI and enable output EO has been provided to allow octal expansion without the need for external circuitry. Efforts are underway to better integrate information from third parties. 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 endorsement thereof.


For instance, if you have 16 inputs but your encoder chip only takes 8 or For all types, data inputs and outputs are active at the low logic level. 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 is not responsible or liable for any 74174 statements. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Pages created and updated by Terry Sturtevant Encodr Posted: The implied decimal zero condition requires no input condition, as zero is encoded when all nine data lines are at a high logic level. 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.

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. 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.

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.

This must be considered when strobing the outputs. The package thermal impedance is calculated in encocer with JESD This is the voltage between two emitters of a multiple-emitter transistor.


datashert 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.

Buyer acknowledges and agrees that it is solely responsible for datashheet 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. Some of these extra pins are what allow these devices to be cascaded.

Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. 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 datawheet actions.

To do this, simply switch the common connections of the keypad and resistor array mentioned above. If you are looking for an office package, with a word processor, spreadsheet, etc.

All input pulses are supplied by generators having the following characteristics: TI bases its knowledge and belief encodsr information provided by third parties, and makes no representation or warranty as to the accuracy of such information.
