9 / 22 page 2003 Jul 10 9 Philips Semiconductors Product specification Dual D-type flip-flop with set and reset; positive-edge trigger 74HC74; 74HCT74 Family 74HCT At recommended operating conditions; voltages are referenced to GND (ground=0V). Note 1. All typical values are measured at Tamb =25 °C. Remark to HCT types The value of additional quiescent supply current ( ∆ICC) for a unit load of 1 is given here. To determine ∆ICC per input, multiply this value by the unit load coefficient shown in the table. SYMBOL PARAMETER TEST CONDITIONS MIN. TYP. MAX.
