5474/DM5474/DM7474
Dual Positive-Edge-Triggered D Flip-Flops
with Preset, Clear and Complementary Outputs
General Description
This device contains two independent positive-edge-trig-
gered D flip-flops with complementary outputs. The informa-
tion on the D input is accepted by the flip-flops on the posi-
tive going edge of the clock pulse. The triggering occurs at a
voltage level and is not directly related to the transition time
of the rising edge of the clock. The data on the D input may
be changed while the clock is low or high without affecting
the outputs as long as the data setup and hold times are not
violated. A low logic level on the preset or clear inputs will
set or reset the outputs regardless of the logic levels of the
other inputs.
Features
Y
Alternate Military/Aerospace device (5474) is available.

utor for specifications.

Absolute Maximum Ratings (Note)
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales
Office/Distributors for availability and specifications.
Note: The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaran-
teed. The device should not be operated at these limits. The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.
