Functional Description
The LVT574 and LVTH574 consist of eight edge-triggered
flip-flops with individual D-type inputs and 3-STATE true
outputs. The buffered clock and buffered Output Enable
are common to all flip-flops. The eight flip-flops will store
the state of their individual D-type inputs that meet the
setup and hold time requirements on the LOW-to-HIGH
Clock (CP) transition. With the Output Enable (OE) LOW,
the contents of the eight flip-flops are available at the out-
puts. When the OE is HIGH, the outputs go to the high
impedance state. Operation of the OE input does not affect
the state of the flip-flops.
