TC74HC173AP/AF
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HC173AP, TC74HC173AF
Quad D-Type Register (3-state)
The TC74HC173A is a high speed CMOS D-TYPE REGISTER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
It consists a 4-bit register consisting of D-type flip-flops and 3-state buffers. The four flip-flops are controlled by a common clock input (CK) and a common clear input (CLR).
Signals applied to the data inputs (D1 to D4) are stored in the respective flip-flops on the positive going transition of CK when clock control inputs (G1, G2) are held low.
The clear function is asynchronous to CK and active on a high level.
