Jul 27, 3. You also need to connect the other inputs to a logic high or a logic low.
Ok, so this is my first post since I’m new to this sn74ls47n datasheet and new to electronics. I’m pretty sure Sn74ls47n datasheet 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.
datasheer Apr 20, 15, Since you are dealing with TTL, any input that is pulled up should have a resistor sn74ls47n datasheet that pin and Vcc. Quote of the day. You Sn74ls47n datasheet Also Like: For 74LSxx, something on the order of 10K is good. Wherever did you come up with that quaint notion?
Jul 27, 4. But there must be individual ohm resistors in the segment lines between the 74LS47 outputs and the display.
He says it could be my resistors. There is still a problem. These are inputs and outputs used in multi digit displays to blank leading zeros. It must be datsheet directly sn74ls47n datasheet the 5 volt sn74ls47n datasheet. My supply is roughly 5v from a parallel portif I’m not mistaken. Jul 27, 6.

Your name or email address: Yes, my password is: Read the datasheet to find out which way they need to go. That one resistor sn74ls47n datasheet the common anode line is incorrect.
And no, my parallel port is sn74ls47nn the prob since I use it to test our previous activity and it worked fine. For CMOS logic, never leave any inputs floating.
Jul 26, 3 0. sn74ls47n datasheet
Do you already sn74ls47n datasheet an account? Use “74ls47” as the term in a search engine to obtain a data sheet for the IC. Discussion in ‘ Homework Help ‘ started by kemzJul 27, Jul 27, 1. I need some enlightenment. For Sn74ls47n datasheet, unconnected inputs float high, but I would not count on it.
If you look at the data sheet for the 74LS47 http: Jul 27, 5.
SN74LS47N Datasheet PDF –
Here is my schematic diagram, I already asked a friend and told him bout my materials but wasn’t able to show sn74ls47n datasheet my schematic. Since 7 segment is also are LEDs put together, how come my previous activity worked fine using same resistors connected to an individual LEDs?
No, create an account now. I just dunno why sn74ls47n datasheet won’t lit up when I put the sn74ls47n datasheet together.
BCD to 7 segment display Posted by diamondking3 in forum: Feb 24, 11, 2, Am I using the right resistors? Mar 8, Jul 28, 7. Jul 27, 2.
