Current Applied to Output. By continuing to use this site, you are agreeing to our use of cookies. Yes, my password is: Data to Output 74F Input Clamp Diode Voltage. 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?


Do you already have an account? Well I suppse I’ll put together the digikey order then. Their cheap and easy to find. They wouldnt have mentioned it unless there was a reason Frankly, if I vaporize the parallel port on my ancient P laptop, I’m not going to be upset. StarbuckT21 Jan Free Air Ambient Temperature.

Absolute maximum ratings are values beyond which the device. You must log in or sign up to reply here.

Input Voltage Note 4. Absolute Maximum Ratings Note 3. Either voltage limit or current limit is sufficient to protect inputs. Ambient Temperature under Bias. Hazer21 Jan Thanks for the advice guys! Input Current Note 4.

Discussion in ‘ Modding ‘ started by StarbuckT21 Jan Data to Output 74F, 74F And they drive any transistor. The only reason I could see for going to an 74HC is to be able to handle a 12V input. The lpt port produces a nice 5v TTL level signal. Very sad that the LS couldn’t give enough output current to drive that.


A critical component in any component of a life support. Output Enable Time 74F Power Supply Current 74F All Other Pins Grounded.

Octal Buffer/Line Driver With 3-STATE Outputs

Alright, that’s pretty much what I figured. 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! Voltage Applied to Output. Specify by appending the suffix letter “X” to the ordering code. Worst-case 74F enabled; 74F, 74F disabled. No, create an account now. Devices also available in Tape and Reel.
