General
The 74HC174D is a high speed CMOS D-TYPE 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.
Information signals applied to the D inputs are transferred to the Q outputs on the positive going edge of the
clock pulse.
When the CLR input is held low, the Q outputs are in the low logic level independent of the other inputs.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
