description
These positive-edge-triggered flipflops implement
D-type flip-flop logic with a direct clear input.
Information at the D inputs that meets the setup
time requirements is transferred to the 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 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.
The 54AC11175 is characterized for operation
over the full military temperature range of − 55°C
to 125°C. The 74AC11175 is characterized for
operation from − 40°C to 85°C.
