The TC74ACT573F(EL) is an octal D-type latch with 3-state outputs manufactured by Toshiba Semiconductor and Storage. It is part of the ACT (Advanced CMOS Technology) family, offering high-speed performance and low power consumption. This latch is commonly used for temporary data storage and buffering in digital systems.

Applications:

• Data Buffering: Temporarily storing data in digital systems for synchronization or data transfer.
• Address Latching: Latching address signals for memory access or peripheral selection.
• I/O Port Expansion: Expanding the number of I/O ports in microcontroller-based systems.
• Microprocessor Systems: Interfacing microprocessors with memory and peripherals.
• Digital Logic Circuits: General-purpose latching applications in digital circuits.

Features:

• Octal Latch: Contains eight D-type latches in a single package.
• 3-State Outputs: Allows the outputs to be in a high, low, or high-impedance state.
• High-Speed Operation: Provides fast propagation delays for high-speed applications.
• Low Power Consumption: Consumes minimal power, making it suitable for battery-powered devices.
• Wide Operating Voltage Range: Operates over a wide voltage range (4.5V to 5.5V).
• Surface Mount Package: Available in a surface mount package for easy assembly.

Benefits:

• Temporary Data Storage: Provides a convenient way to store data temporarily.
• System Integration: Simplifies system design by integrating eight latches into a single package.
• High-Speed Performance: Enables fast and reliable data transfer.
• Reduced Power Consumption: Minimizes power consumption, extending battery life in portable devices.
• Versatile Application: Suitable for a wide range of digital logic applications.

Additional Details:

The TC74ACT573F(EL) is controlled by a latch enable (LE) input. When LE is high, the outputs follow the data inputs. When LE is low, the outputs are latched and remain constant, regardless of changes at the data inputs. The output enable (OE) input controls the 3-state outputs. When OE is low, the outputs are enabled; when OE is high, the outputs are in a high-impedance state. Refer to the official Toshiba Semiconductor datasheet for detailed specifications, timing diagrams, and application examples. The device is sensitive to static discharge.
