TheAnimus21 Jan 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 74f2444 interfaced to a pc parallel port? You must log in or sign up to reply here. Data to Output 74F And they drive any transistor.
Voltage Applied to Output. The lpt port produces a nice 5v TTL level signal. Current Applied to Output. Your fatasheet or email address: All Other Pins Grounded.
Hazer21 Jan StarbuckT21 Jan Ambient Temperature under Bias. The only problem with the parport is that some can only source 2ma, but that shouldn’t be a problem, just remeber if you go for TTL enabled cmos, nice 10k pullups!

They wouldnt have mentioned it unless there was a reason Log in or Sign up. Their cheap and easy to find.
A critical component in any component of a life support. Frankly, if I vaporize the parallel port on my ancient P laptop, I’m not going to be upset.
Physical Dimensions inches millimeters unless otherwise noted Continued. Share This Page Tweet. Input Voltage Note 4.
Data to Output 74F, 74F Power Supply Current 74F Fairchild does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and. Thanks for the advice guys! It also consumes the most supply current. Yes, my password is: The directions say that “avoid 74LSs because they don’t 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.
Physical Dimensions inches millimeters unless otherwise noted. The 74F, 74F and 74F are octal buffers and line.

Recognized as a LOW Signal. I mainly stick to 74HC series. Absolute Maximum Ratings Note 3.
datawheet Input Clamp Diode Voltage. Input Current Note 4. Do you already have an account? Alright, that’s pretty much what I figured. Junction Temperature under Bias.
