74LVQ273
Low Voltage Octal D-Type Flip-Flop
General Description
The LVQ273 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 in-
put, 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 de-
vice is useful for applications where the true output only is re-
quired and the Clock and Master Reset are common to all
storage elements.
Features
n Ideal for low power/low noise 3.3V applications
n Implements patented EMI reduction circuitry
n Available in SOIC JEDEC, SOIC EIAJ and QSOP
packages
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Improved latch-up immunity
n Guaranteed incident wave switching into 75
n 4 kV minimum ESD immunity

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