Since 7 segment is also are LEDs put together, how come my previous sn74ls47n datasheet worked fine using same resistors connected to an individual LEDs?

My supply is roughly 5v from a parallel portif I’m not mistaken. For 74LSxx, something on the order of sn74ls47n datasheet is good.

Jul 26, 3 0. Do you already have an account? BCD to 7 segment display Posted by diamondking3 in forum: I just dunno why it won’t lit up when I put the things together. Here is my schematic diagram, I already asked a sn74ls47n datasheet and sn74ls47n datasheet him bout my materials but wasn’t able to show him my schematic.


Since you are dealing with TTL, any input daatsheet is pulled up should have a resistor between sn74ls47n datasheet pin and Vcc. Apr 20, 15, For CMOS logic, never leave any inputs floating. Jul 27, 6. Sn74ls47n datasheet must be tied directly to the 5 volt source. Read the datasheet to find out which way they need to go. He says it could be my resistors. Your name or email address: These are inputs and outputs used in multi digit displays to blank leading zeros.

That one resistor in the common anode line is incorrect. There is still a problem.

sn74ls47n datasheet Quote of the day. 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

You also need to connect the other inputs to a logic high or a logic low. You May Also Sn74ls47n datasheet Jul 27, 4. Discussion in ‘ Homework Help ‘ started by kemzJul 27, Ok, so this is my first post since I’m new to this forum and new to electronics. Wherever did you come up with that quaint notion? I need some enlightenment. Jul 27, 2. Jul 27, 3. Jul 27, 5. Use “74ls47” as the term in a sn74ls47n datasheet engine to obtain a sn74ls47n datasheet sheet for the IC.


No, create an account now.

But there must be individual ohm resistors in the segment lines between the 74LS47 outputs and the display.
