54F 74F534 Octal D-Type Flip-Flop with TRI-STATE Outputs May 1995 54F 74F534 Octal D-Type Flip-Flop with TRI-STATE Outputs General Description The ’F534 is a high speed low-power octal D-type flip-flop 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 ’F534 is the same as the ’F374 except that the outputs are inverted Features Y Y Y Y Edge-triggered D-type inputs Buffered positive edge-triggered clock TRI-STATE outputs for bus-oriented applications

DIP SOIC and Flatpak Pin Assignment for LCC TL F 9549 – 3 TL F 9549–2 Functional Description The ’F534 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 Function Table Inputs CP L L L X OE L L L H D H L X X Output O L H O0 Z H e HIGH Voltage Level L e LOW
