Hitachi HD74HC534
HD74HC534 is only that the former is a true outputs and the latter is a false outputs. When a high logic level is applied to the output control (OC) input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.| Part No. | HD74HC534 |

DESCRIPTION
These devices are positive edge triggered flip-flops. The difference between HD74HC374 and Data at the D inputs, meeting the setup and hold time requirements, are transferred to the Q outputs on positive going transitions of the clock (CK) input.FEATURES
