Description

These devices are positive edge triggered flip-flops. The difference between HD74HC374 and HD74HC534 is only

that the former is a true outputs and the latter is a false outputs. 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. 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.
