74LVX74
Low Voltage Dual D-Type Positive Edge-Triggered
Flip-Flop
General Description
The LVX74 is a dual D-type flip-flop with Asynchronous
Clear and Set inputs and complementary (Q, Q) outputs.
Information at the input is transferred to the outputs on the
positive edge of the clock pulse. After the Clock Pulse input
threshold voltage has been passed, the Data input is
locked out and information present will not be transferred to
the outputs until the next rising edge of the Clock Pulse
input.
Asynchronous Inputs:
LOW input to SD (Set) sets Q to HIGH level
LOW input to CD (Clear) sets Q to LOW level
Clear and Set are independent of clock
Simultaneous LOW on CD and SD makes both Q and Q
HIGH
Features
s Input voltage level 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.
