Thanks for the advice guys! Alright, that’s pretty much what I figured. I mainly stick to 74HC series. Junction Temperature under Bias. Absolute maximum ratings are values beyond which the device.

Log in or Sign up. Do you already have dstasheet 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.

Check the datasheet probably best, i have mostly given up descrete stuff. Your name or email address: Physical Dimensions inches millimeters unless otherwise noted Continued. From what Ive read and remember: The only problem with the parport is 7f4244 some can only source 2ma, but that shouldn’t be a problem, just remeber if you go for TTL enabled cmos, nice 10k pullups!
As far as the 74F, isn’t that just a ‘Fast’ chip? Worst-case 74F enabled; 74F, 74F disabled.
Devices also available in Tape and Reel. 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? TheAnimus21 Jan Output Disable Time 74F Input Clamp Diode Voltage. Fairchild does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and. Frankly, if I vaporize the parallel port on my ancient P laptop, I’m not going to be upset.

It also consumes the most supply current. All Other Pins Grounded. Well I suppse I’ll put together the digikey order then.
And they drive any transistor. Very sad that the LS couldn’t give enough output current to drive that. A critical component in any component of a life support. StarbuckT21 Jan Hazer21 Jan Their cheap and easy datasehet find.

Data to Output 74F, 74F Recognized as a 74ff244 Signal. The 74F, 74F and 74F are octal buffers and line. No, create an account now. I was aware of the dahasheet current limitation, which is why it is unwise to use an unbuffered JTAG.
Current Applied to Output. Output Enable Time 74F Specify by appending the suffix letter “X” to the ordering code. They wouldnt have mentioned it unless there was a reason Power Supply Current 74F Absolute Maximum Ratings Note 3.
