(3-State, Non-Inverting)
The MC74LVQ574 is a high performance, non–inverting octal D–type
flip–flop operating from a 2.7 to 3.6V supply. The MC74LVQ574 is
suitable for TTL level bus oriented applications where a memory element
is required.
Current drive capability is 12mA at the outputs. The MC74LVQ574
consists of 8 edge–triggered flip–flops with individual D–type inputs and
3–state true outputs. The buffered clock and buffered Output Enable (OE)
are common to all flip–flops. The eight flip–flops will store the state of
individual D inputs that meet the setup and hold time requirements on the
LOW–to–HIGH Clock (CP) transition. With the OE LOW, the contents of
the eight flip–flops are available at the outputs. When the OE is HIGH, the
outputs go to the high impedance state. The OE input level does not affect
the operation of the flip–flops.
