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.

74F244 Datasheet

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.

Very sad that the LS couldn’t give enough output current to drive that. Free Air Ambient Temperature. No, create an account now. By continuing to use this site, you are agreeing to our use of cookies.

Physical Dimensions inches millimeters unless otherwise noted Continued. Share This Page Tweet. Input Voltage Note 4.

I was aware of the low current limitation, which is why it is unwise to use an unbuffered JTAG. From what Ive read and remember: Well I suppse I’ll put together the digikey order then. Output Enable Time 74F The only reason I could see for going to an 74HC is to be able to handle a 12V input. Life support devices or systems are devices or systems. Absolute maximum ratings are values beyond which the device. Output Disable Time 74F Discussion in ‘ Modding ‘ started by StarbuckT21 Jan This site uses cookies.


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.
