NSC DM54175W Hex/quad d flip-flops with clear Datasheet

54174/DM54174/DM74174, 54175/DM54175/DM74175
Hex/Quad D Flip-Flops with Clear
General Description
Features
These positive-edge triggered flip-flops utilize TTL circuitry
to implement D-type flip-flop logic. All have a direct clear
input, and the quad (175) version features complementary
outputs from each flip-flop.
Information at the D inputs meeting the setup and hold time
requirements is transferred to the Q outputs on the positivegoing edge of the clock pulse. Clock triggering occurs at a
particular voltage level and is not directly related to the transition time of the positive-going pulse. When the clock input
is at either the high or low level, the D input signal has no
effect at the output.

174 contains six flip-flops with single-rail outputs
175 contains four flip-flops with double-rail outputs
Buffered clock and direct clear inputs
Individual data input to each flip-flop
Applications include:
Buffer/storage registers
Shift registers
Pattern generators
Typical clock frequency 40 MHz
Typical power dissipation per flip-flop 38 mW
Alternate Military/Aerospace device (54174, 54175) is
available. Contact a National Semiconductor Sales Office/Distributor for specifications.

Absolute Maximum Ratings (Note)
Note: 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’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales
Office/Distributors for availability and specifications.
