4-Digit 7-Segment Display - Yellow

sku: COM-09480

Description: This is a basic, 4-digit 7-segment display - yellow in color. It has a common anode. The display features one decimal point per digit, and individually controllable apostrophe and colon points.

The LEDs have a forward voltage of 2.1VDC and a max forward current of 20mA. The hardware interface is sixteen (two rows of eight) through-hole pins.

We carry this same display in red, green, and blue.

Note: The pinout in the datasheet is incorrect. This is the correct pin-out:

1: Digit 1	16: B
2: Digit 2	15: G
3: D	14: A
4: Colon Anode	13: C
5: E	12: Colon Cathode
6: Digit 3	11: F
7: Decimal Point	10:Apostrophe Anode
8: Digit 4	9: Apostrophe Cathode

Dimensions:

Overall Display: 40.18 x 12.8 mm (1.58 x 0.50")
Digit Height: 10mm (0.39")

so to clarify, this is an almost identical product to the yellow one you used to sell, except it has a different pin layout? and a different amount of pins?

That's correct, Greeg. Both displays are the exact same size. The footprints are similar (same pin-spacing), however this display has all 16-pins connected (and a function for each pin), rather than the 14 on the older display.

Jimb0: That's correct, Greeg. Both displays are the exact same size.

If so, what are the functions for pins 14 to 16? Datasheet only covers pins 1 to 13.

I read that go the datasheet too. I'm hoping that those pins (14,15,16) are N/C's because in my design i'll need to cut them off, i'm just wanting to confirm before i send off my board designs.

So, it turns out the pin-out in the datasheet is incorrect. The correct pin-out is now posted on the product page. Sorry about that!

that's a shame, but thanks for clearing that up for us. one last question is the display common anode like in the datasheet? or is it common cathode?

nevermind it says that in the 2nd line, i just didn't notice it :D

I just bought the 14 pin one before the new 16 pin one came out. What datasheet do i read?????

Here's a link to the datasheet it sounds like you'll need: http://www.sparkfun.com/datasheets/Components/C4727JS.pdf. Sorry that info isn't more prevalent.
