Inputs and outputs are active low. For instance, if you have 16 inputs but your encoder chip only takes 8 or The LEDs may be connected backwards, plus each one needs a ballast resistor. 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.

That looks like a in your circuit and not having GS or EO connected to something sensible could make all the difference. Device is in production to support existing customers, but TI does not recommend using this part in a new design. Jasen 9, 14 The outputs are measured one at a time, with one input transition per measurement.

Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. 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 emcoder basis. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.


This component has a RoHS exemption for either 1 lead-based flip-chip solder bumps used between the die and package, or 2 741447 die adhesive used between the die and leadframe. This is the voltage between two emitters of a multiple-emitter transistor.

For all types, data inputs and outputs are active at the low logic level. Device has been announced but is not in production.

If you need to update a browser, you might try Firefox which is free open source available for several platforms Since this page 741447 cascading style sheets for its layout, it will look best with a browser which supports the specifications as fully as possible. Note that while the inputs are active lowthe outputs are active high. All diodes are 1N or equivalent. 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.

If a line is 774147 then it is a continuation of the previous line and the two combined represent the entire Top-Side Marking for that device.

This means that you will want a key pressed to give a low output on the corresponding line. Post as a guest Name.

To do this, simply switch the common connections of the keypad and resistor array mentioned above. Pages created and updated by Terry Sturtevant Date Posted: It has a few additional inputs and outputs compared to the This must be considered when strobing the outputs.

Buyer 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 dagasheet requirements jc connection with such use.


Nonetheless, such components are subject to these terms. Sometimes you have more inputs than can be used with a single encoder chip. Decimal to Binary encoder in proteus Ask Question.
