The MC74LVX74 is an advanced high speed CMOS D-type flip-flop. The inputs tolerate voltages up to 7V, allowing the interface of 5V systems to 3V systems. The signal level applied to the D input is transferred to O output during the positive going transition of the Clock pulse. Clear (CD) and Set (SD) are independent of the Clock (CP) and are accomplished by setting the appropriate input Low.
