应用功能：四三态R-S锁存触发器("0"触发) NSC/MOT/TI CD4044BM/CD4044BC are quad cross-couple TRI-STATE CMOS NAND latches. Each latch has a separate Q output and individual SET and RESET inputs. There is a common TRI-STATE ENABLE input for all four latches. A logic ``1'' on the ENABLE input connects the latch states to the Q outputs. A logic ``0'' on the ENABLE input disconnects the latch states from the Q outputs resulting
