The TC74HC564A and HC574A are high speed CMOS OCTAL
FLIP-FLOPs with 3-STATE OUTPUT fabricated with silicon gate
C2MOS technology.
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.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
