2 / 8 page ©1988 Fairchild Semiconductor Corporation www.fairchildsemi.com 74ACT534 Rev. 1.4 2 Functional Description The ACT534 consists of eight edge-triggered flip-flops with individual D-type inputs and 3-STATE complemen- tary 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 times requirements on the LOW-to- HIGH Clock (CP) transition. With the Output Enable (OE) LOW, the contents of the eight flip-flops are avail- able at the outputs. When the 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 H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial = LOW-to-HIGH Clock Transition Z = High Impedance O0 = Value stored from previous clock cycle Logic Diagram Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays.
