1/5pcs TI CD4043BM CMOS Quad NOR R/S Latch with 3-State Outputs 3-18V SOIC-16

Description

1/5pcs TI CD4043BM CMOS Quad NOR R/S Latch with 3-State Outputs 3-18V SOIC-16
CD4043B types are quad cross-coupled 3-state CMOS NOR latches and the CD4044B types are quad cross-coupled 3-state CMOS 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 busing of the outputs.
