The HD74HC175FP is a high-speed silicon gate CMOS quad D-type flip-flop with complementary outputs, fabricated with silicon gate CMOS technology. It achieves speeds similar to equivalent LSTTL while maintaining the low power dissipation inherent in CMOS integrated circuits. Each flip-flop is a D-type flip-flop, and all four flip-flops share a common clock (CK) and a common clear (CLR) input.
