Hello,
Specs are defined differently for TLIN1029-Q1's LIN VOH and VOL below and above VSUP = 7 V. For example, the Min VOH is a ratio (× 0.85) of VSUP for VSUP of 7 V and above while it's a voltage (3 V) for VSUP of less than 7 V. The same is applied to VOL, too. I suspect it comes from the internal architecture, but what exactly is the reason behind this?
Best regards,
