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 are transferred to the outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of CLK. Following the holdtime interval, data at the D input can be changed without affecting the levels at the outputs. Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) SN74HC74N...
