You can use the IC as the encoder in this case. What am I doing wrong? Device has been dataseet but is not in production.

TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release. CL includes probe and jig capacitance. Home Questions Tags Users Unanswered. Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the rncoder control.

Samples may or may not be available. All diodes are 1N or equivalent. This must be considered when strobing the outputs. Decimal to Binary encoder in proteus Ask Question.

Inputs and outputs are active low.

PC/CP Cascading Encoders

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.

Cascading circuitry enable input EI and enable output EO has been provided to allow octal expansion without the need for external circuitry. Sign up using Email and Password. TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

That looks like a in your circuit and not having GS or EO connected to something sensible could make all the difference.


It’s a community-based project which helps to repair anything. 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.

Buyers are responsible for datashewt products and applications using TI components. All input pulses are supplied by generators having the following characteristics: TI has discontinued the production of the device. Product device recommended for new designs. Buyer represents and agrees that it has all ddatasheet 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 remedial actions.

The information provided on this page represents TI’s knowledge and belief as of the date that it is provided. Make sure power is connected too. The package thermal impedance is calculated in accordance with JESD Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. Ideally you want to choose a large value that works consistently. Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control.

If you are looking for an office package, with a word processor, spreadsheet, etc. 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.

Jasen 9, 14 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. 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. Encoder Chip Sometimes you have more inputs than can be used with a single encoder datasheef.


Sometimes you have more inputs than can be used with a single encoder chip. Exposure to absolute-maximum-rated conditions for extended darasheet may affect device reliability.

Device is in production to support enncoder customers, but TI does not recommend using this part in a new design. The implied decimal zero condition requires no input condition, as zero is encoded when all nine data lines are at a high logic level.

TI is not responsible or liable for any such statements. Sign up using Facebook. To do this, simply switch the common connections of the keypad and resistor array mentioned above. Voltage values, except inter-emitter voltage, are with respect to the network ground terminal. 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.

This means that you will want a key pressed to give a low output on the corresponding line. Efforts are underway to better integrate information from third parties.

Phase relationships between inputs and outputs have been chosen arbitrarily for these examples. Products Applications Audio www.


TI is not responsible or liable for such ecnoder documentation. 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 dagasheet device. Not 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.
