TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HC74AP,TC74HC74AF
Dual D-Type Flip Flop Preset and Clear
The TC74HC74A is a high speed CMOS D FLIP FLOP
fabricated with silicon gate C
2
MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The signal level applied to the D INPUT is transferred to Q
OUTPUT during the positive going transition of the CLOCK
pulse.
CLEAR
and
PRESET
are independent of the CLOCK and
are accomplished by setting the appropriate input to an “L” level.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
