CD4044集成电路（IC）的锁存器规格书PDF中文资料

描述 Description

CD4043BMS types are quad cross-coupled 3-state CMOS NOR latches and the CD4044BMS 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, results in an open circuit feature allows common busing of the outputs.
