74HC574 Tri State Octal D Type Flip Flop IC (74574) DIP 20 Package

74HC574 Tri State Octal D Type Flip Flop IC (74574) DIP 20 Package

The 74HC574 is a high-speed CMOS Octal D-Type Edge-Triggered Flip-Flop with 3-State Outputs.
It consists of eight D-type flip-flops with individual data inputs and corresponding outputs, all sharing a common clock (CP) and a common output enable (OE).

Data at each input (D0–D7) is transferred to the corresponding output (Q0–Q7) on the rising edge of the clock pulse. When the OE (Output Enable) input is LOW, the outputs are active. When OE is HIGH, the outputs go to a high-impedance (Hi-Z) state, allowing easy connection to a data bus without interference.
