Data to Output 74F, 74F Ratasheet only reason I could see for going to an 74HC is to be able to handle a 12V input. As far as the 74F, isn’t that just a ‘Fast’ chip?

StarbuckTdatazheet Jan I mainly stick to 74HC series. Physical Dimensions inches millimeters unless otherwise noted Continued. The lpt port produces a nice 5v TTL level signal. Specify by appending the suffix letter “X” to the ordering code. No, create an account now. The 74F, 74F and 74F are octal buffers and line.

It also consumes the most supply current. Log in or Sign up. Junction Temperature under Bias. Datasheett does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and. Yes, my password is: The directions say that “avoid 74LSs because they 74f24 work with the wide range of voltages put out by some parallel ports” This seems bunk to me, a lot of 74LS series chips I’ve seen take some pretty darn high input voltages without vaporizing themselves.

Your name or email address: Voltage Applied to Output. They wouldnt have mentioned it unless there was a reason Either voltage limit or current limit is sufficient to protect inputs.

Recognized as a LOW Signal.

Well Dayasheet suppse I’ll put together the digikey order then. Output Disable Time 74F Check the datasheet probably best, i have mostly given up descrete stuff. You must log in or sign up to reply here.

Ambient Temperature under Bias. The only problem with the parport is that some can only source 2ma, but that shouldn’t be a datsaheet, just remeber if you go for TTL enabled cmos, nice 10k pullups! Absolute Maximum Ratings Note 3. Share This Page Tweet. Their cheap and easy to find.

Current Applied to Output. All Other Pins Grounded. TheAnimus21 Jan Data to Output 74F Life support devices or systems are devices or systems.


From what Ive read and remember: Output Enable Time 74F Free Air Ambient Temperature. And they drive any transistor. Absolute maximum ratings are values beyond which the device. I’ll just pull one of my 8 PMMX integrated everything boards out of the closet and fry it to So is there any logic to the argument that a 74HC would be better than a 74LS interfaced to a pc parallel port? Power Supply Current 74F Physical Dimensions inches millimeters unless otherwise noted. Frankly, if I vaporize the parallel port on my ancient P laptop, I’m not going to be upset.

Worst-case 74F enabled; 74F, 74F disabled. Very sad that the LS couldn’t give enough output current to drive that. By continuing to use this site, you are agreeing to our use of cookies.

Input Current Note 4. Alright, that’s pretty much what I figured.
