3.3V signals to 5V using the 74HC4050D @ 3.3V and 74HC541 @ 5V.
Worst case you don’t even meet the 0. I can never remember.
Email Required, but never shown. Olin Lathrop k 30 I may be misreading the datasheet, but I think you are: For input high a minimum of 3. I’m attempting to perform some logic level conversions on 3.
Before the industrial revolution, there were a lot of those around in Europe and elsewhere. PS I’m aware of that the datahseet current into these devices Icc is about 50ma and a max output of a particular pin Io is around ma.
Whether that is sufficiently below 3.
This Microchip document shows some interesting ways to interface between 3. I don’t even know if it’s a common name in neighboring Germany. No, I know that “Schmidt” must be one of the most occurring names, Dataasheet meant “Schmitt”. Good beginner questions; 3. Thanks for your reference document.
I remember because it’s the only Schmitt I know. Linearly extrapolating to 5 V that becomes 3.
But its output is a 3. The chip is a down-voltage converter and cannot be used at all for up converting.

Is it only leakage current that would be output in this 74nc4050d Could you elaborate on this please Tony ” The chip is a down-voltage converter hex buffer. So if you need a logic gate in there anyway, make it a HC T type and you get the 3.
Tony EE rocketscientist Links for you reference: In the datasheets you have to look for minimum high level input and maximum low level input. Low level input should be less dataheet 1.
