Dual Positive-Edge-Triggered D-type Flip-Flops With Clear And Preset
descriptionThese devices contain two independent positive-
edge-triggered D-type flip-flops. A low level at the
preset (PRE) or clear (CLR) inputs sets or resets
the outputs regardless of the levels of the other
inputs. When PRE and CLR are inactive (high),
data at the data (D) input meeting the setup time
requirements is transferred to the outputs on the
positive-going edge of the clock pulse. Clock
triggering occurs at a voltage level and is not
directly related to the rise time of the clock pulse.
Following the hold-time interval, data at the
D input may be changed without affecting the
levels at the outputs.
The SN54F74 is characterized for operation over
the full military temperature range of –55°C to
125°C. The SN74F74 is characterized for
operation from 0°C to 70°C.
FUNCTION TABLE†The output levels are not guaranteed to meet the
minimum levels for VOH. Furthermore, this
configuration is nonstable; that is, it will not persist
when PRE or CLR returns to its inactive (high)
level.
