The IDT74ALVC16841PA is a 20-bit bus interface D-type latch with 3-state outputs manufactured by Renesas Electronics America. It belongs to the Advanced Low-Voltage CMOS (ALVC) logic family, designed for high-speed, low-power applications requiring data latching in bus-oriented systems.

Applications:

• Memory Addressing: Used in memory systems for addressing and data buffering.
• Data Buffering: Employed in systems requiring temporary data storage on a bus.
• Bus Interface: Facilitates data transfer between different buses or systems.
• Microprocessor Systems: Integrated into microprocessor-based systems for address latching and data buffering.
• Industrial Control: Used in industrial control systems for data buffering and latching in I/O interfaces.

Features:

• 20-Bit Latch: Provides latching for 20 bits of data simultaneously.
• 3-State Outputs: Allows the outputs to be disabled, effectively disconnecting the device from the bus.
• Low Voltage Operation: Operates at low voltage levels, typically 3.3V or 2.5V.
• High-Speed Performance: Offers fast propagation delays due to the ALVC technology.
• Low Power Consumption: ALVC technology ensures low power consumption.
• TTL Compatible Inputs: Accepts TTL input voltage levels.

Benefits:

• Improved System Performance: Latches data, allowing other bus operations to proceed without interruption.
• Reduced Bus Loading: 3-state outputs minimize bus loading when the device is not actively driving the bus.
• Lower Power Consumption: Low-voltage operation contributes to energy efficiency.
• Faster Data Transfer: High-speed performance ensures rapid data latching and transfer.
• Simplified System Design: TTL compatible inputs simplify interfacing with other logic families.

Additional Details: The 'PA' suffix typically indicates the package type, which is often a plastic DIP (Dual In-line Package) or a similar through-hole package. Key parameters like propagation delay, supply voltage range, and input/output voltage levels are specified in the Renesas datasheet. The IDT74ALVC16841 is widely used in systems requiring efficient data latching and bus management. Always refer to the official Renesas datasheet for complete specifications and application notes before use. The datasheet provides detailed information on timing characteristics, power consumption, and pin configurations.
