Sn74ls47n datasheet the datasheet to find out which way they need to go. For TTL, unconnected sn74,s47n float high, but I would not count on it. Your name or email address: For 74LSxx, something on the order of 10K is good.
You also need to connect the other inputs to a logic high or a logic low. sn74ls47n datasheet
Mar 8, Am I using the right resistors? I just dunno why it won’t lit up when I put the sn74ls47n datasheet together.
Jul 27, 1. Since 7 segment is also are LEDs put together, how come my an74ls47n activity worked fine using same resistors connected to an individual LEDs? No, create an account now. That one resistor in the common anode line is incorrect. Jul sn74ls47n datasheet, 4. There datasneet still a problem. Discussion in ‘ Homework Help ‘ sn74ls47n datasheet by kemzJul 27, Ok, so this is my first post since I’m new to this forum and new to electronics. Do you sn74ls47n datasheet have an account?
Use “74ls47” as the term in a search engine to obtain a data sheet for the Sn74ls47n datasheet. My supply is roughly 5v from a parallel portif I’m not mistaken. But there must be individual ohm resistors in the segment sn74lls47n between the 74LS47 outputs and the display. Sn74ls47n datasheet, my password is: Wherever did you come up with that quaint notion?
Jul 28, 7. It must be tied directly to the 5 volt source.
Since you are dealing with TTL, any input that is pulled sn74ls47n datasheet should have a resistor between that pin and Vcc. Jul 26, 3 0.
Sn74s47n of the day. Jul 27, 3. If you look at the data sheet sn74ls47n datasheet the 74LS47 http: For CMOS sn74ls47n datasheet, never leave any inputs floating.
These are inputs and outputs used in multi digit displays to blank leading zeros. Feb 24, 11, 2, BCD datahseet 7 segment display Fatasheet by diamondking3 in forum: Here is my schematic diagram, I already asked a friend and told him bout my materials but wasn’t able to show him my schematic.
Apr 20, 15, Jul 27, 6. You May Also Like: I need some enlightenment. I’m pretty sure I connected the IC-to-7segment right, when I tested my seven segment using a multi-tester, it lits up which means it’s OK and functioning.

He says it could be my resistors. And no, my parallel port is not the prob since I use it sn74ls47n datasheet test our previous activity and it worked fine. Jul 27, 2. Jul 27, 5.
