description

The 'AC74 are dual 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 theother inputs. When and are inactive (high), data at thedata (D) input meeting the setup-time requirements is transferred tothe outputs on the positive-going edge of the clock pulse. Clocktriggering occurs at a voltage level and is not directly related tothe rise time of the clock pulse. Following the hold-time interval,data at D can be changed without affecting the levels at the outputs.

The SN54AC74 is characterized for operation over the full militarytemperature range of -55°C to 125°C. The SN74AC74 ischaracterized for operation from -40°C to 85°C.
