UKŁAD SCALONY: CD4043
CD4043B types are quad cross-coupled 3-state CMOS NOR latches and the CD4040B types are quad cross-coupled 3-state CMOS NAND laches. Each latch has a separate Q output and individual SET and RESET inputs. The Q outputs arecontrolled by a common ENABLE input. A logic "1" or high on the ENABLE input connects the latch states to the Q outputs. A logic "0" or low on the ENABLE input disconnects the latch states from the Q outputs, resulting in an open circuit condition on the Q outputs. The open circuit feature allows common businf of the outputs.
