Functional Description
Truth Table
The VHC574 consists of eight edge-triggered flip-flops with
individual D-type inputs and 3-STATE true outputs. The
Inputs
buffered clock and buffered Output Enable are common to
all flip-flops. The eight flip-flops will store the state of their
individual D inputs that meet the setup and hold time
requirements on the LOW-to-HIGH Clock (CP) transition.
