Hello
You said that the X1243BIGABL does not support cascading and we will need to order the XA1243FPBGABL instead.
Is your datasheet reliable?
because we have bought the X1243BIGABL based on the datasheet (SWRS188 –MAY 2017, page 4), in which you mentioned the IC supports cascading but in 2018 version (oct.10,2018) is said the IC does not.
Thanks for your attention.
