74LVX273
Low Voltage Octal D-Type Flip-Flop
General Description
The LVX273 has eight edge-triggered D-type flip-flops with
individual D inputs and Q outputs. The common buffered
Clock (CP) and Master Reset (MR) input load and reset
(clear) all flip-flops simultaneously.
The register is fully edge-triggered. The state of each D
input, one setup time before the LOW-to-HIGH clock transi-
tion, is transferred to the corresponding flip-flop’s Q output.
All outputs will be forced LOW independently of Clock or
Data inputs by a LOW voltage level on the MR input. The
device is useful for applications where the true output only
is required and the Clock and Master Reset are common to
all storage elements. 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

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.
