SN7400: Topside part marking

Kevin Korn

Part Number: SN7400

Tool/software:

What does the part marking CLO denote for TI part # SN74LVC1G57DCKR with 0627 date codes (year = 2006, week = 27). Attached is a picture that our customer supplied with the top side marking of the part #.

thank you, Kevin

Or the marking could be CLD. Sorry, a tad difficult to make out in the picture the customer provided. thank you, Kevin

Hi Kevin,

The "C" indicates device family, the "L" indicates the device function code, and the last digit indicates the fab/assembly site code.

Best,

Malcolm

Can you please define the last character assembly site, appears to be an "O" or "D". Can you provide a definition for both?

thank you much! Kevin

Hi Kevin,

It might be a "Q" which would indicate it's from HFAB, which is my best guess here. I don't see anything for "O" or "D" in the system, it would help if you told me what A/T the part is from or if I had a picture of the shipping label.

Best,

Malcolm

Hello Malcolm, Here is a photo of the label. If we can define the last digit of Q or O or D from the CL* marking that'd be great! Please provide city and country if possible.

Hi Kevin,

I responded this on another thread that asked the same question, but since this is an old part (date marking indicates 2006) it looks like it's from an old flow, so I'm not sure exactly where it came from (besides Thailand). However the part looks legitimate; this is a valid marking.

Best,

Malcolm
