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 : MC74AC573, MC74ACT573 Octal Buffer/Line Driver with 3-State Outputs The MC74AC573/74ACT573 is a high−speed octal latch with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs. The MC74AC573/74ACT573 is functionally identical to the MC74AC373/74ACT373 but has inputs and outputs on opposite sides. Features • Inputs and Outputs on Opposite Sides of Package Allowing Easy Interface with Microprocessors • Useful as Input or Output Port for Microprocessors • Functionally Identical to MC74AC373/74ACT373 • 3−State Outputs for Bus Interfacing • Outputs Source/Sink 24 mA • ′ACT573 Has TTL Compatible Inputs • These are Pb−Free Devices VCC O0 O1 O2 O3 O4 O5 O6 O7 LE 20 19 18.
