I just sn74ls47n datasheet why it won’t lit up when I put the things together. Here is my sn74ls47n datasheet diagram, I already asked a friend and told him bout my materials but wasn’t able to show him my schematic. For 74LSxx, something on the order of 10K is good.
Use “74ls47” as the term in a search sn74ls47n datasheet to obtain a data sheet for the IC. No, create an account now. Jul 27, 1. Am I using the right resistors?
Jul 27, 5. But there must be individual ohm resistors in the segment lines between the 74LS47 outputs sn74ls47n datasheet the display.
Jul 27, 4. If you look at the data sheet for the 74LS47 http: Jul 28, 7.
For CMOS logic, never leave any inputs floating. Yes, my password is: Jul 26, sn74ls447n 0. Feb 24, 11, 2, My supply is roughly 5v from a parallel portif I’m not mistaken. You May Also Like: Since 7 segment is sn74ls47n datasheet are LEDs put together, how come sn74ls47n datasheet previous activity worked fine using same resistors connected to an sn74ls47n datasheet LEDs?
Discussion in ‘ Homework Help ‘ started by kemzJul 27, For TTL, unconnected inputs sn74ls47n datasheet high, but I would not count on it. Mar 8, 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.
SN74LS47N Datasheet PDF –
Jul 27, 3. Jul 27, 2.
Read the datasheet to find out which way they need to go. I need some enlightenment. It must be tied directly to the 5 volt source. That one resistor in datsaheet common anode line is incorrect. And no, my parallel port is not the prob since I use sn74ls47n datasheet to test our previous activity and it worked fine. These are inputs and outputs used in multi digit displays to blank leading zeros. Quote of the day. Wherever did you come up sn74ls47n datasheet that sn74ls47n datasheet notion?
He says it could be my resistors.

Apr 20, 15, Since you are dealing with TTL, sn74ls47n datasheet input that is pulled up should have a resistor between that pin and Vcc. Do you already have an account? Ok, so this is my first post since I’m new to this forum and new to electronics. Jul 27, sn74ls47n datasheet.
Daatasheet name or email address: You also need to connect the other inputs to a logic high or a logic low.
There is still a problem. BCD to 7 segment display Posted by diamondking3 in forum:
