54ACT 74ACT534 Octal D Flip-Flop with TRI-STATE Outputs March 1993 54ACT 74ACT534 Octal D Flip-Flop with TRI-STATE Outputs General Description The ’ACT534 is a high-speed low-power octal D-type flipflop featuring separate D-type inputs for each flip-flop and TRI-STATE outputs for bus-oriented applications A buffered Clock (CP) and Output Enable (OE) are common to all flip-flops The ’ACT534 is the same as the ’ACT374 except that the outputs are inverted Features Y Y Y Y Y Y Y ICC and IOZ reduced by 50% Edge-triggered D-type inputs Buffered positive edge-triggered clock TRI-STATE outputs for bus-oriented applications Outputs source sink 24 mA ’ACT534 has TTL-compatible inputs Inverted output version of ’ACT374 Logic Symbols IEEE IEC Connection Diagrams Pin Assignment for DIP Flatpak

F 9965 RRD-B30M75 Printed in U S A Functional Description The ’ACT534 consists of eight edge-triggered flip-flops with individual D-type inputs and TRI-STATE complementary 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 available 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 Logic Diagram TL F 9965 – 5 Please note that this diagram is provided only for the understanding of logic operations and should not be used to
