The TC74VHC373FT ELK is an Octal D-Type Latch with 3-State Outputs manufactured by Toshiba Semiconductor and Storage. It is part of the VHC (Very High-Speed CMOS) logic family, offering high-speed operation with low power consumption. This device is commonly used for temporary data storage and data bus interfacing in digital systems.

Applications

• Data Bus Buffering: Provides temporary storage of data being transferred on a data bus.
• Address Latching: Used to latch address information in memory systems.
• Microprocessor Systems: Implemented as part of microprocessor memory interface.
• Peripheral Interfacing: Serves as latch for transferring data between a microprocessor and peripheral devices.
• Digital Data Storage: General purpose storage of digital information.

Features

• Octal Latch: Contains eight independent D-type latches.
• 3-State Outputs: Provides 3-state outputs, allowing the outputs to be enabled, disabled (high impedance), or driven to a high or low logic level.
• High-Speed Operation: Offers high-speed operation with a typical propagation delay of around 5 ns.
• Low Power Consumption: Consumes minimal power due to its CMOS technology.
• Wide Operating Voltage Range: Operates over a wide voltage range, typically from 2V to 5.5V.
• Enable Control: Includes an enable input to control the latching of data.
• Small Outline Package: Available in a TSSOP package for space saving and surface mounting.

Benefits

• Efficient Data Storage: Provides efficient temporary storage of data.
• Flexible Data Bus Interfacing: The 3-state outputs allow for flexible data bus interfacing.
• Improved System Performance: High-speed operation improves overall system performance.
• Reduced Power Consumption: Low power consumption contributes to energy efficiency.
• Simplified System Design: Wide operating voltage range simplifies system design and reduces component count.
