Descriptions:

The 74HC574A is an edge-triggered flip-flop with a common clock (CP) and output enable (OE) control. Data is transferred to the outputs on the positive edge of the clock. The outputs enter a high-impedance state when OE is high.

Features:

• Octal D-type flip-flop with 3-state outputs
• Positive-edge triggered clock input
• Common output enable (OE) control
• Wide operating voltage range (2V to 6V)
• High noise immunity
• Low power consumption
• Compatible with TTL levels
• Latch-up performance exceeds 250 mA per JESD78

This device is commonly used in bus interface, register storage, and data buffering applications.
