- Definition(s)
- A resistor used to pull a logic input "up" to the high state, or logic-1 state, thus preventing a disconnected input from floating into an undetermined state. Sealevel Systems, Inc.
- Example sentence(s)
- Without an internal pull-up enabled in our circuit, the button would be "floating" when open and ground when pushed. We want it to be a digital high when open. We need the pull-up resistor. - Micah Carrick
by - Once again, modern parts require lower currents, but if a switch seems to be unreliable, try increasing the current by reducing the value of the pull-up resistor. - The errant engineer
by - So determine if parts count or cost come into play with this design, are you building 3 prototypes or 10,000 units [to determine the cost and impact of the resistor]. Next determine if the resistor is really required, check the IC logic family being used, it may or may not require a pull-up resistor. - Leroy Davis

- Term
- resistencia de polarizacion
- Additional fields of expertise
- Definition(s)
- El término es ampliamente utilizado como resistencia pull-up, o resistencia de polarización para indicar a aquella que posee uno de sus terminales al positivo de la fuente de alimentación. Entre sus diferentes usos encontramos los siguientes:
Polarizaciones, como por ejemplo para los transistores,se conectaría a la alimentación del colector y otro a la salida del mismo.
Elevación de la tensión de salida para un dispositivo digital. wikipedia - by Maria Mercau
- Example sentence(s)
- Las resistencias de Pull-Down consiste en una resistencia puesta entre una línea y masa. A diferencia de las de Pull-Up tienen como objetivo dar a esa línea un valor lógico de nivel bajo de masa (0V) cuando no hay ninguna señal conectada.
En electrónica analógica sirven para distintos propósitos, adaptar impedancias de línea, estabilizar la salida de un amplificador operacional, polarización, etc. - foros de electronica

- Rezistenţă de ridicare ( la 1)
- Additional fields of expertise
- Definition(s)
- E o rezistenţă folosita la ridicarea intrarii logice la "1", prevenind astfel o intrare lasata in gol de la "plutirea" intr-o stare (logica) nehotarata.
Sealevel Systems, Inc - by ION CAPATINA
- Example sentence(s)
- "Atât rezistenţele de ridicare la "1" cât şi cele de coborâre la "0" sunt folosite in circuitele logice electronice pentru a asigura că intrările la sistemele logice se stabilizează la valorile logice aşteptate atunci când se deconectează dispozitivele externe de impedanţă mare. " - Wikipedia
by ION CAPATINA - “ Pentru ca atunci când nu există activitate pe magistrală toate liniile să aibă acelaşi potenţial, acestea se conectează prin rezistenţe de ridicare la “1”. - Universitatea Tehnica din Cluj
by ION CAPATINA - „o rezistenţă externă de ridicare (nu interna) se foloseşte ca atunci când pinul e în aer, să aibă o valoare stabilă de 1 (deparazitare, într-un fel). astfel, un buton (de exemplu) care face/taie un circuit, va scoate la iesire două stări, masa (dacă e legat la masă într-o parte) şi V+ prin pullup când e deschis.” - Forum electronisti
