This device contains two independent positive-edge-triggered
D-type flip-flops. A low level at the preset () or clear () input sets or resets the outputs
regardless of the levels of the other inputs. When and are inactive (high), data at the
data (D) input that meets the setup-time requirements are transferred
to the outputs on the low-to-high transition of the clock (CLK)
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 74AC11074 is characterized for operation from -40°C to
85°C.
