The SN54LVC74A is designed for 2.7-V to 3.6-V VCC operation, and the SN74LVC74A is designed for 1.65-V to 3.6-V VCC operation. 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. Clock triggering occurs at a voltage level ...
