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 meeting 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 74ACT11074 is characterized for operation from -40°C to 85°C.
