LM158: Device marking of "LM158JG/883B"

Liu Yang

Part Number: LM158

Hi Team,

One of my customers want to confirm whether the atteched is the TI's real product.
If yes, what is the part number of Device marking of "LM158JG/883B"?
What confused us is that we can find device marking of "LM158JG" but can not find "LM158JG/883B"
on TI's website.

Beat Regards,
Tom Liu

Hello Tom,

This appears to be the old marking under the old part name.

The new name is LM158JGB. It looks like this. All 'x' can vary

According to the National Semiconductor Device Marking Conventions (devicemarkingconventions.pdf), "/883" refers to MIL-STD-883 processing.
