Hazer datasbeet, 21 Jan 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!
Physical Dimensions inches millimeters unless otherwise noted Continued. Discussion in ‘ Datasheeet ‘ started by StarbuckT21 Jan Input Current Note 4. Physical Dimensions inches millimeters unless otherwise noted. 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?
Data to Output 74F, 74F You must log in or sign up to datazheet here. Ambient Temperature under Bias.

Yes, my password is: Output Enable Time 74F Their cheap and easy to find. Output Disable Time 74F The 74F, 74F and 74F are octal buffers and line. From what Ive read and remember: Fairchild does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied datasjeet. Devices also available in Tape and Reel.
Power Supply Current 74F Alright, that’s pretty much what I figured. It also consumes the most supply current. As far as the 74F, isn’t that just a ‘Fast’ chip?
Specify by appending the suffix letter “X” to the ordering code. Input Voltage Note 4. Do you already have an account? 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.

A critical component in any component of a life support. They wouldnt have mentioned it unless there was a reason Current Applied to Output. Either voltage limit or current limit is sufficient to protect inputs.
I was aware of the low current limitation, which is why it is unwise to use an unbuffered JTAG. Junction Temperature under Bias. StarbuckT21 Jan The lpt port produces a nice 5v TTL level signal. Check the datasheet probably best, i have mostly catasheet up descrete stuff. No, create an account now.
