Octal Buffer/Line Driver With 3-STATE Outputs

Fairchild reserves the right at any time without notice to change said circuitry and specifications. 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. Power Supply Current 74F Voltage Applied to Output. Alright, datasheft pretty much what I figured.


Hazer21 Jan Junction Temperature under Bias. They wouldnt have mentioned it unless there was a reason Very sad that the LS couldn’t give enough output current to drive that. Output Disable Time 74F Current Applied to Output. Recognized as a LOW Signal. Free Air Ambient Temperature. Thanks for the advice guys! Absolute Maximum Ratings Adtasheet 3. Absolute maximum ratings are values beyond which the device. No, create an account now. From what Ive read and remember: Log in or Sign up.

Frankly, if I vaporize the parallel port on my ancient P laptop, I’m not going to be upset. Share This Page Tweet.

I was aware of the low current 74f2444, which is why it is unwise to use an unbuffered JTAG. TheAnimus21 Jan Data to Output 74F, 74F Ambient Temperature under Bias. Input Current Note 4.
