DM74LS174 • DM74LS175
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. All have a direct clear
input, and the quad (175) versions feature 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.

s Applications include:
Buffer/storage registers
Shift registers
Pattern generators
s Typical clock frequency 40 MHz
s Typical power dissipation per flip-flop 14 mW
