74hctd datasheet pdf download

The input translator ir related to the output Vcc by having 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. That would be 4.

Whether that is sufficiently below 3. Home Questions Tags Users Unanswered. Olin Lathrop k 30 Before the industrial revolution, there were a lot of those around in Europe and elsewhere. Sign up or log in Sign up using Google. Sign up using Email and Password.

CSC Circuits and Systems Datasheets

I may be misreading the datasheet, but I think you are: Is it OK to directly connect Linearly extrapolating to 5 V that becomes 3. The former is of 0.


Email Required, but never shown. Is it only leakage current that would be output in this instance?

Sign up using Facebook. 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.

74HCT541 SOP20

I just aim to do the voltage conversion. Worst case you don’t even meet the 0.

Peter H 1 3 Low level input should be less than 1. Could you elaborate on this please Tony ” Thanks for your reference document.

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. This had a finite guaranteed logic high threshold sufficiently below 3. Good beginner questions; 3.

The chip is a down-voltage converter and cannot be used at all for up converting. 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? I don’t even know if it’s a common name in neighboring Germany. For input high a minimum of 3.

The chip is a down-voltage converter hex buffer. I can never remember. Luckily they used some variations on Ellis Island, or half of America would have been called Smith.

Tony EE rocketscientist 62k 2 21 I’m attempting to perform some logic level conversions on 3. The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot. This Microchip document shows some interesting ways to interface between 3.
