The input translator ir related to the output Vcc by having a threshold slightly more than Vcc so that a translator range of 2: First off the noise immunity is imbalanced so that potential risk from ingress noise is imbalanced. I just aim to do the voltage conversion. The dataseet is a down-voltage converter hex buffer. 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”.

Before the industrial revolution, there were a lot of those around in Europe and elsewhere. In the datasheets you have to look for minimum high level input and maximum low level input. No, I know that “Schmidt” must be one of the most occurring 74hc541r, I meant “Schmitt”. Sign up using Email and Password. Post as a guest Name. Email Required, but never shown.

Is it OK to directly connect Peter H 1 3 But its output is a 3. I can never remember.

I guess my question is without resistors connected how would one know whether it’s safe to connect the outputs of the 74HCD to datashet inputs of the 74HC as this chip can do the logic conversion? A beginner style question.

The chip is a down-voltage converter and cannot be used at all for up converting. This Microchip document shows some interesting ways to interface between 3. Home Questions Tags Users Unanswered. The risk depends level of noise from ingress for long dataasheet or, cross-talk, conducted noise or overshoot. I’m attempting to perform some logic level conversions on 3.

Whether that is sufficiently below 3. Is it only leakage current that would be output in this instance? Worst case you don’t even meet the 0. For input high a minimum of 3. 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. Links for you reference: That would be 4. Could you elaborate on this please Tony ” By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policydataseet that your continued use of the website is subject to these policies.

Olin Lathrop k 30 Luckily they used some variations on Ellis Island, or half of America would have been called Smith.


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

This had a finite guaranteed logic high threshold sufficiently below 3. It doesn’t help that another local EE I know has the last name “Schmidt”.

Good beginner questions; 3. Tony EE rocketscientist 62k 2 21 I remember because it’s the only Schmitt I know. The former is of 0. Linearly extrapolating to 5 V that becomes 3.

Low level input should be less 74hc54d1 1. I don’t even know if it’s a common name in neighboring Germany. 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.
