SEMICONDUCTOR TECHNICAL DATA
"
!
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
accomplished by setting the appropriate input Low.
) and Set (SD) are independent of the Clock (CP) and are
