The HCC4043B, HCC4044B, (extended temperature range) and the HCF4043B, HCF4044B (intermediate temperature range) are monolithic integrated circuits, available in 16-lead dual in-line plastic or ceramic package and plastic micropackage. The HCC/HCF4043B types are quad crosscoupled 3-state COS/MOS NOR latches and the HCC/HCF4044B types are quad cross-coupled 3state COS/MOS NAND latches. 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 bussing of the outputs. June 1989
