74LVX574
Low Voltage Octal D-Type Flip-Flop with
3-STATE Outputs
General Description
The LVX574 is a high-speed octal D-type flip-flop which is
controlled by an edge-triggered clock input (CP) and a buff-
ered common Output Enable (OE) input. When the OE
input is HIGH, the eight outputs are in a high impedance
state. The LVX574 is functionally identical to the LVX374
but with inputs and outputs on opposite sides of the pack-
age. The inputs tolerate up to 7V allowing interface of 5V
systems to 3V systems.
Features
s Input voltage translation from 5V to 3V
s Ideal for low power/low noise 3.3V applications
s Guaranteed simultaneous switching noise level and
dynamic threshold performance

Functional Description
The LVX574 consists 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 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 outputs. When the OE is
HIGH, the outputs go to the high impedance state. Opera-
tion of the OE input does not affect the state of the flip-
flops.

Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.
