BCD to 7 segment display Posted by diamondking3 in forum: Since 7 segment is also are LEDs put together, how come sn74ls47n datasheet previous activity worked fine using same resistors datasheeet to an individual LEDs?
Here is my schematic diagram, I already asked a friend and told him bout my materials but wasn’t able to show him my sn74ls47n datasheet.
For 74LSxx, something on the sn74ls47n datasheet of 10K is good. He says it could be my resistors. Jul 27, 3.
Quote of the day. Jul 27, 2. For CMOS logic, never leave any inputs floating. Use “74ls47” as the term in a search engine to obtain a data sn74ls47m for the IC. I just dunno why it won’t sn74ls47n datasheet up when I put the things together. Feb 24, 11, 2, There is still a ddatasheet. But there must sn74ls47n datasheet individual ohm resistors in the segment lines between the 74LS47 outputs and the display.
Sn74ls47n datasheet name or sn74ls47n datasheet address: No, create an account now. Jul 27, 1. Jul fatasheet, 6. You also need to connect the other inputs to a logic high or a logic low.
Do you already have an account? Since you are dealing with TTL, any input that is pulled up should have a resistor between that pin and Vcc.
If you look at the data sheet for the 74LS47 http: Jul sn74ls47n datasheet, 4. Am I using the sn74ls47n datasheet resistors? Mar 8, I need some enlightenment. Read the datasheet to find out which way they need to go.
My supply is roughly 5v from a parallel portif I’m sn74ls47n datasheet mistaken. For TTL, unconnected inputs float high, but I would not count on it. These sn74ls47n datasheet inputs and outputs used in multi digit displays to blank leading zeros.
You May Also Like: It must be tied directly to the 5 volt source. Jul 26, 3 0. Discussion in ‘ Homework Help ‘ sn74ls47n datasheet by kemzJul 27, Yes, my password is: And no, my parallel port is not the prob since I use it to test our previous sn74ls47n datasheet and it worked fine.

Apr 20, 15, Jul 27, 5. That one resistor in the common anode line is incorrect. Ok, so this sn74ls47n datasheet my first post since I’m new to this forum and new to electronics. I’m pretty sure I connected the IC-to-7segment right, when I tested my seven segment using a multi-tester, it sn74ls47n datasheet up which means it’s OK and functioning. Wherever did you come up with that quaint notion?
