SN74AHCT74 Overview
The ’AHCT74 dual positive-edge-triggered devices are D-type flip-flops. 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) input meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock pulse.
SN74AHCT74 Key Features
