74HC573

The 74HC573 is an octal D-type transparent latch engineered for high-speed operation and dependable data storage in digital electronics. Designed with high-speed CMOS technology, this 8-bit wide latch provides simultaneous data capture across multiple channels while maintaining low quiescent current and high noise immunity for stable performance in electrically noisy environments.

• 8-bit wide latch configuration enables parallel storage and transfer of byte-wide data.
• Operating voltage range: 2V to 6V ensures compatibility with a broad range of logic families and systems.
• Typical propagation delay ~13 ns supports fast switching and responsive timing in high-speed designs.
• Low quiescent current helps minimize power consumption in battery-powered and energy-conscious applications.
• High noise immunity preserves signal integrity where electrical interference may be present.

Its transparent-latch behavior gives designers flexible timing control: when the latch enable is active, inputs propagate to outputs; when disabled, data is held stable at outputs. This characteristic simplifies interface timing between asynchronous subsystems, allows controlled data sampling, and supports bus-hold strategies where predictable output states are required.

Integration and Reliability

The 74HC573 is suited for use in general-purpose digital circuits, embedded systems, address and data buffering, and any application requiring temporary parallel data storage with fast access. The device’s controlled timing characteristics and low power profile make it practical for synchronous designs where deterministic capture and hold times are critical. Built for reliable operation across a broad temperature range, the IC helps maintain system stability under varied environmental conditions.
