The M74HCT574 is a high performance CMOS eight-bit D-type flip-flop with 3-state output, with inverted function.
The M74HCT574 is a high-speed CMOS octal D-type flip-flop with 3-state outputs, fabricated using sub-micron silicon gate CMOS technology. It is designed to be pin and function compatible with the 74 series 574. The device is controlled by a clock input (CK) and an output enable input (OE), allowing data to be set on the positive transition of the clock while outputs can be placed in a high-impedance state.

Yes, it is compatible with TTL outputs with a minimum input high voltage of 2.0V.
When the OE input is high, the outputs will be in a high impedance state.
