operation.
dual
positive-edge-triggered
D-type
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) inputs 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 can be changed without affecting the
levels at the outputs.
The SN54LV74A is characterized for operation over the full military temperature range of –55
