HD74BC534A Octal D Type Flip Flops With 3 State Outputs ADE-205-012 (Z) Rev. 0 June 1993 Description The HD74BC534A provides high drivability and operation equal to or better than high speed bipolar standard logic IC by using Bi-CMOS process. The device features low power dissipation that is about 1/5 of high speed bipolar logic IC, when the frequency is 10 MHz. The device has eight edge triger D type flip flop with three state outputs in a 20 pin package. Data at the D inputs meeting set up reguirements, are transferred to the Q outputs on positive going transitions of the clock input. When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again. When a high logic level is applied to the output control input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the strage elements. Features • • • • Input/Output are at high impedance state when power supply is off. Built in input pull up circuit can make input pins be open, when not used.
