Good beginner questions; 3.

I can never remember. Post as a guest Name.

This had a finite guaranteed logic high threshold sufficiently below 3. Home Questions Tags Users Unanswered. The input translator ir related to the output Vcc by datashdet a threshold slightly more than Vcc so that a translator range of 2: So if you need a logic gate in there anyway, make it a HC T type and you get the 3.

First off the noise immunity is imbalanced so that potential risk from ingress noise is ddatasheet. That would be 4. 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.

So unless you are trying to do a closed-loop or loopback test?

I don’t even know if it’s a common name in neighboring Germany. The chip is a down-voltage converter and cannot be used at all for up converting.

Whether that is sufficiently below 3. Could you elaborate on this please Tony ” By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. I remember because it’s the only Schmitt I know. Olin Lathrop k 30 This Microchip document shows some interesting ways to interface between 3. The former is of 0. Before the industrial 74hc451d, there were a lot of those around in Europe and daatasheet.

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

I guess my question is without resistors 74h5c41d 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? 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.

I may be misreading the datasheet, but I think you are: Sign up using Email and Password. Thanks for your reference document. I’m attempting to perform some logic level conversions on 3. Tony EE rocketscientist 62k 2 21 But its output datwsheet a 3. In the datasheets you have to look for minimum high level input and maximum low level input. For input high a minimum of 3. I just aim to do the voltage conversion.

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

Low level input should be less than 1. The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot. Peter H 1 3 A beginner style question.
