The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot.

Before the industrial revolution, there were a lot of those around datashedt Europe and elsewhere. So unless you are trying to do a closed-loop or loopback test?

3.3V signals to 5V using the 74HC4050D @ 3.3V and 74HC541 @ 5V.

Worst case you don’t even meet the 0. Home Questions Tags Users Vatasheet. In the datasheets you have to look for minimum high level input and maximum low level input. Sign up using Email and Password.

Good beginner questions; 3. Could you elaborate on this please Tony ” Linearly extrapolating to 5 V that becomes 3. First off the noise immunity is imbalanced so that potential risk from ingress noise is imbalanced. The input translator ir related to the output Vcc by having a threshold slightly more than Vcc so that a translator range of 2: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.


But its output is a 3. I may datashedt misreading the datasheet, but I think you are: I can never remember. The chip is a down-voltage converter hex buffer. This Microchip document shows some interesting ways to interface between 3. That would be 4.

Is it OK to directly connect Links for you reference: 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.

The chip is a down-voltage converter and cannot be used at all for up converting. This had a finite guaranteed logic high threshold sufficiently below 3. It is pronounced more like “shmeet” would be in english, but means exactly the same as “smith”, which refers to the profession today called “blacksmith”.

For input high a minimum of 3. I just aim to do the voltage conversion. Thanks for your reference document.

I’m attempting to perform some logic level conversions on 3. 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 datashwet as this chip can do the logic conversion?


What should I be looking for in terms of the 74hc4050x when determining these things in 74hc40050d case I don’t really aim to source or sink current to other devices. Is it only leakage current that would be output in this instance?

So if you need a logic gate in there anyway, make it a Datasneet T type and you get the 3. I don’t even know if it’s a common name in neighboring Germany. It doesn’t help that another local EE I know has the last name “Schmidt”.

No, I know that “Schmidt” must be one of the most occurring names, I meant “Schmitt”.


Low level input should be less than 1. Sign up or log in Sign up using Google. Peter H 1 3 Tony EE rocketscientist Olin Lathrop k 30 Email Required, but never shown. A beginner style question.
