Vladimir,
I apologize for this delay in responding to your post.
It does appear as though that the TLC4545 is not reset correctly during power up – possibly because of some digital or analog input being applied before the power supplies are stable…
Other Parts Discussed in Thread: TLC4545 Hello,
When we are using TLC4545, 2 LSB (D0 and D1) are always set at 1.
Is their any special procedure to get these 2 LSB?
Best regards.
