Low-Voltage Quiet CMOS

Octal D-Type Flip-Flop

(3-State, Non-Inverting)

The MC74LVQ374 is a high performance, non–inverting octal D–type

flip–flop operating from a 2.7 to 3.6V supply. The MC74LVQ374 is

suitable for TTL level bus oriented applications where a memory element

is required.

Current drive capability is 12mA at the outputs. The MC74LVQ374

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.
