ISO7742: Need advise the way understand characters in MPN

Hi Dai,

Thanks for reaching out and for your interest in ISO7742.

Please see below FAQ that briefly explains how to interpret the characters in part numbers for digital isolator devices. Let me also explain specifically the "QDBQQ1" in part number ISO7742QDBQQ1. The first letter "Q" means this is an automotive grade part, "DBQ" is the package code for QSOP package and "Q1" states that this is a grade 1 automotive part that supports a temperature range of -40C to 125C. Q1 is for grade 1 while Q0 is for grade 0 automotive part supporting -40C to 150C temperature range.
