Hex Quad D Flip-Flops with Clear
General Description
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 positive-
going edge of the clock pulse Clock triggering occurs at a
particular voltage level and is not directly related to the tran-
sition 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
Features
Y
174 contains six flip-flops with single-rail outputs
Y
175 contains four flip-flops with double-rail outputs
Y
Buffered clock and direct clear inputs
Y
Individual data input to each flip-flop
Y
Applications include
Buffer storage registers
Shift registers
Pattern generators
Y
Typical clock frequency 40 MHz
Y
Typical power dissipation per flip-flop 38 mW

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
