DM74ALS174 • DM74ALS175 Hex/Quad D-Type Flip-Flops with Clear
DM74ALS174 • DM74ALS175
Hex/Quad D-Type Flip-Flops with Clear
General Description
These positive-edge-triggered flip-flops utilize TTL circuitry
to implement D-type flip-flop logic. Both have an asynchro-
nous clear input, and the quad (DM74ALS175) version fea-
tures complementary outputs from each flip-flop.
Information at the D inputs meeting the setup time require-
ments is transferred to the Q outputs on the positive-going
edge of the clock pulse. Clock triggering occurs at a partic-
ular 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.
Features
Advanced oxide-isolated ion-implanted Schottky TTL
process
Pin and functional compatible with LS family counterpart
Typical clock frequency maximum is 80 MHz
Switching performance guaranteed over full temperature

Absolute Maximum Ratings(Note 2)
Note 2: 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.
