Functional Description
HIGH Voltage Level Voltage Level High Impedance Immaterial Previous before LOW-to-HIGH Transition Clock
MC74AC573/74ACT574 contains eight D-type latches with 3-state output buffers. When Latch Enable (LE) input HIGH, data inputs enters latches. this condition latches transparent, i.e., latch output will change state each time input changes. When latches store information that present inputs setup time preceding HIGH-to-LOW transition 3-state buffers controlled Output Enable (OE) input. When LOW, buffers enabled. When HIGH buffers high impedance mode this does interfere with entering data into latches.
NOTE:
