Nexperia 74HCD, – PDF Datasheet – 74 Series In Stock |

I’m attempting to perform some logic level conversions on 3. Tony EE rocketscientist This had a finite guaranteed logic high threshold sufficiently below 3. I remember because it’s the only Schmitt I know. It is pronounced more like “shmeet” would be in english, but means exactly the same as “smith”, which refers to the profession today called dztasheet.

Email Required, but never shown.

Is it only leakage current that would be output in this instance? Good beginner questions; 3. I can never remember. 74hc405d its vatasheet is a 3.

What should I be looking for in terms of the datasheets when determining these things in my case I don’t really aim to source or sink current to other devices. It doesn’t help that another local EE I know has the last name “Schmidt”. That would be 4. Sign up using Facebook.

The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot. In the datasheets you have to look for minimum high level input and maximum low level input.

Linearly extrapolating to 5 V that becomes 3. I may be misreading the datasheet, but I think you are: I just aim to do the voltage conversion.

74HC4050D Datasheet

The chip is a down-voltage converter hex buffer. This Microchip document shows some interesting ways to interface between 3.

So if you need a logic gate in there anyway, make it a HC T type and you get the 3. Olin Lathrop k 30 Links for you reference: I don’t even know if it’s a common name in neighboring Germany. First off the noise immunity is imbalanced so that potential risk from ingress noise is imbalanced. I guess my question is without resistors connected how would one know whether it’s safe to connect the outputs of the 74HCD to the inputs of the 74HC as this chip can do the logic conversion?

Post as a guest Name. The input translator ir related to the output Vcc by having a threshold slightly more than Vcc so that a translator range of 2: Sign up using Email and Password.

A beginner style question. Before the industrial revolution, there were a lot of those around in Europe and elsewhere. PS I’m aware of that the maximum current into these devices Icc is about 50ma and a max output of a particular pin Io is around ma.

Home Questions Tags Users Unanswered. The chip is a down-voltage converter and cannot be used at all for up converting.

Worst case you don’t even meet the 0.
