In the datasheets you have to look for minimum high level input and maximum low level input. Tony EE rocketscientist It doesn’t help that another local EE I know has the last name “Schmidt”.

I can never remember. Sign up or log in Sign up using Google. The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot. That would be 4. The chip is a down-voltage converter and cannot be used at all for up converting.

Home Questions Tags Users Unanswered. The chip is a down-voltage converter hex buffer. Sign up using Email and Password. I’m attempting to 744hc4050d some logic level conversions on 3. So unless you are trying to do a closed-loop or loopback test? Links for you datahseet So if you need a logic gate in there anyway, make it a HC T type and you get the 3. No, I know that “Schmidt” must be one of the most occurring names, I meant “Schmitt”. Olin Lathrop k 30 The former is of 0.

Could you elaborate on this please Tony ” This had a finite guaranteed logic high threshold sufficiently below 3. 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. Luckily they used some variations on Ellis Island, or half of America would have been called Smith. The input translator ir related to the output Vcc by having a threshold slightly more than Vcc so that a translator range of 2: For input high a minimum of 3. First off the noise immunity is imbalanced so that potential risk from ingress noise is imbalanced.

Is it only leakage current that would be output in this instance? 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”.


Sign up using Facebook. Worst case you don’t even meet the 0. I remember because it’s the only Schmitt I know. Linearly extrapolating to 5 V that becomes 3. A beginner style question. Post as a guest Name. Good 74hc4050s questions; 3.

74HCD Datasheet(PDF) – NXP Semiconductors

I don’t even know if it’s a common name in neighboring Germany. Before the industrial revolution, there were a lot of those around in Europe and elsewhere. Whether that is sufficiently below 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 74HC as this chip can do the logic conversion?

Low level input should be less than 1. Peter H 1 3 Thanks for your reference document. Is it OK to directly connect Email Required, but never shown. 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. I may be misreading the datasheet, but I think you are:
