Octal Buffer/Line Driver With 3-STATE Outputs

Input Voltage Note 4. From what Ive read and remember: 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! Fairchild does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and. Their cheap and easy to find. I mainly stick to 74HC series.

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?


74F244 Datasheet

As far as the 74F, isn’t that just a ‘Fast’ chip? Physical Dimensions inches millimeters unless otherwise noted Continued. Yes, my password is: Voltage Applied to Output. Devices also available in Tape and Reel.

Share This Page Tweet. The only reason I could see for going to ratasheet 74HC is to be able to handle a 12V input. Do you already have an account?

Hazer21 Jan And they drive any transistor. Worst-case 74F enabled; 74F, 774f244 disabled. They wouldnt have mentioned it unless there was a reason The 74F, 74F and 74F are octal buffers and line.

Output Disable Time 74F Absolute maximum ratings are values beyond which the device. Specify by appending the suffix letter “X” to the ordering code. Alright, that’s pretty much what I figured. StarbuckT21 Jan Fairchild reserves the right at any time without notice to change said circuitry and specifications. Power Supply Current 74F Data to Output 74F, 74F Either voltage limit or current limit is sufficient to protect inputs.


Data to Output 74F Your name or email address: Input Current Note 4. Output Enable Time 74F Thanks for the advice guys!

Input Clamp Diode Voltage. Free Air Ambient Temperature. Ambient Temperature under Bias. I was aware of the low current limitation, which is why datasgeet is unwise to use an unbuffered JTAG. The lpt port produces a nice 5v TTL level signal.
