HD74HCT374RP Diagram
描述
These devices are positive-edge triggered flip-flops. The difference between HD74HCT374 and HD74HCT534 is 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.
