Texas Instruments SN74AHC74/SN74AHC74Q-Q1 D-Type Flip-Flops

Texas Instruments SN74AHC74/SN74AHC74Q-Q1 D-Type Flip-Flops are dual positive-edge-triggered devices. A low level at the preset (PRE) or clear (CLR) inputs sets or resets the outputs. This is done 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 can be changed without affecting the levels at the outputs. The Texas Instruments SN74AHC74Q-Q1 devices are AEC-Q100 qualified for automotive applications.
