TC74HC564AF Overview
They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. These 8-bit D-type flip-flops are controlled by a clock input (CK) and an output enable input ( OE ). The TC74HC564A has inverting outputs, and the TC74HC574A has non-inverting outputs.
