Start of the CD4504B datasheet says: TTL to CMOS, the SELECT input is at Vcc. When the SELECT input is LOW, CMOS to CMOS. This seems to be contradicted by the legends under figs 9 and 10 of 2004 datasheet, (8,9 of 2008 datasheet). Which is correct?

when select is high it is TTL so the charts are wrong. We will get them corrected.
