MC74AC57 : The MC74AC574/74ACT574 consists of eight edgetriggered flip-flops with individual D-type inputs and 3-state true outputs. The buffered clock and buffered Output Enable are common to all flip-flops. The eight flip-flops will store the state of their individual D inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CP) transition. With the Output Enable (OE) LOW, the contents of the eight flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high impedance state. Operation of the OE input does not affect the state of the flip-flops. FUNCTION TABLE Inputs OE H H H H L L L L CP H H D L H L H L H L H Internal Q NC NC L H L H NC NC Outputs Funct.
MC74AC573 : The MC74AC573/74ACT574 contains eight D-type latches with 3-state output buffers. When the Latch Enable (LE) input is HIGH, data on the Dn inputs enters the latches. In this condition the latches are transparent, i.e., a latch output will change state each time its D input changes. When LE is LOW the latches store the information that was present on the D inputs a setup time preceding the HIGH-to-LOW transition of LE. The 3-state buffers are controlled by the Output Enable (OE) input. When OE is LOW, the buffers are enabled. When OE is HIGH the buffers are in the high impedance mode but this does not interfere with entering new data into the latches. LOGIC DIAGRAM D0 D1 D2 D3 D4 D5 D6 D7 D.
