Device is in production to support existing customers, but TI does not recommend using this part in a new design.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. 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.

Post as a guest Name. Ideally you want to choose a large catasheet that works consistently. This must be considered when strobing the outputs. Try turning off all but sw2. Phase relationships between inputs and outputs have been chosen arbitrarily for these examples.

The LEDs may be connected backwards, plus each one needs a ballast resistor. Device has been announced but is not in production. Sign up using Facebook. Samples may or may not be encooder. Not recommended for new designs. Decimal to Binary encoder in proteus Ask Question. TI is not responsible or liable for any such statements. It’s a community-based project which helps to repair anything.

Sometimes you have more inputs than can be used with a single encoder chip. Email Required, but never shown. 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.


The package thermal impedance is calculated in accordance with JESD That looks like a in your circuit and not having GS or EO connected to something sensible could make all the difference. 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 datashdet continued use of the website is subject to 741477 policies. In some cases, TI components may be promoted specifically to facilitate safety-related applications.

Information of third parties may be subject to additional restrictions. The implied decimal zero condition requires no input condition, as zero is encoded when all nine data lines are at a high logic level.

PC/CP Cascading Encoders

It has a few additional inputs and outputs compared to the Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Resources To view pdf documents, you can download Adobe Acrobat Reader.

What am I doing wrong? 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.

Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the output control.

Efforts are underway to better integrate information from third parties. Jasen 9, 14 Active low inputs In some cases, such as this, you will be using the keypad for input to devices which use active low inputs.

TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. In some cases, such as this, you will be using the keypad for input to devices which use active low inputs. Pages created and updated by Terry Sturtevant Date Posted: Resale of TI darasheet 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.


Below is the schematic for how to cascade two s to give a single 4 bit output. Eatasheet 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.

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 regulatory requirements in connection with such use.
