HD74HC374/HD74HC534
Octal D-type Flip-Flops (with 3-state outputs)
Octal D-type Flip-flops (with inverted 3-state outputs)
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.
