CD4043BE SR tri-state latch / logic chip

The CD4043BE is a CMOS quad NOR R/S Latch with 3-state outputs. Each latch has a separate Q output and individual SET and RESET inputs. The Q outputs are controlled 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 busing of the outputs.
