Jul 27, 5. Your name or email address: These are inputs and outputs used in multi digit displays dwtasheet blank leading zeros. Jul 27, 4.

Jul 27, 3. Am I using the right resistors? Apr 20, 15, Jul 27, 2. Quote of the day.

Feb 24, sn74lss47n, 2, And no, sn74ls47n datasheet parallel port is not the prob since I use it to test our previous activity and it worked fine. You May Also Sn74ls47n datasheet For TTL, unconnected inputs float high, but I would not count on it.


Jul 27, 1. Wherever sn74ls47n datasheet you come up with that quaint notion? Ok, so this is my first post since I’m new dataseet this forum and new to electronics. Jul 28, 7.

SN74LS47N Datasheet –

sn74ls47n datasheet There is still a problem. But there must be individual ohm resistors in the segment lines between the 74LS47 outputs and the display.

Jul 27, 6. No, create an account now.

Do you already have an account? He says it could be my resistors. It must sn74ls47n datasheet tied directly to the 5 sn74s47n source. Yes, my password is: Mar 8, That one resistor in the common anode line is incorrect. You also sn74ls47n datasheet to connect the other inputs to a logic high or a logic low.

SN74LS47N Datasheet(PDF) – ON Semiconductor

sn74ls47n datasheet Discussion sn74ls47n datasheet ‘ Homework Help ‘ started by kemzDatahseet 27, 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. 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. Jul 26, 3 0.


I need some enlightenment. Use “74ls47” as the term in a search engine to obtain a data sheet for sn74ls47n datasheet IC. For CMOS logic, never leave any inputs floating.

Access Denied

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: For 74LSxx, something on the sn74ls47n datasheet of 10K is good.

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