Part Number: SN74LV14A

Hi team,

Could you please elaborate on the following marking changes due to PCN?

My customers do not understand what ECAT value G4 and unit ID coordinate mean.

Regards,

ECAT is the environmental category. G4 has no meaning nowadays; see [FAQ] Why does a logic device's part number have an E4/G4 suffix?

The unit ID coordinate is part of the lot trace code information, which is not public information. It sounds like the position of the die on the wafer.
