The IDT74FCT16841CTPV, manufactured by Renesas Electronics America (originally IDT), is a high-speed 20-bit bus interface D-type latch. This device is part of the FCT (Fast CMOS Technology) family, designed for high-performance applications requiring fast data transfer rates and minimal propagation delay. Its primary function is to latch data present on the input bus and hold it until the latch enable signal is asserted again, allowing for synchronous data handling in digital systems.

Applications

• High-speed memory interfacing.
• Data buffering in digital signal processing (DSP) systems.
• Cache memory systems.
• Bus isolation and data storage in embedded systems.
• Level translation between different voltage domains.

Features

• 20-bit wide latch.
• Fast CMOS Technology (FCT) for high-speed operation.
• TTL-compatible inputs.
• Low propagation delay.
• 3-state outputs for bus isolation.
• Available in TSSOP package.
• Operates at 5V supply voltage.

Benefits

• Improved system performance due to high-speed data latching.
• Enhanced data integrity with stable output signals.
• Reduced signal skew due to low propagation delay.
• Flexible integration with TTL-compatible logic.
• Simplified bus management with 3-state outputs.

Additional Details

The IDT74FCT16841CTPV is specifically designed for applications requiring high-speed data retention and retrieval. The 20-bit wide latch allows for parallel data processing, making it suitable for memory systems and bus interfacing applications. The device's TTL-compatible inputs simplify integration with other logic devices. Its low propagation delay minimizes the time required to latch and output data, contributing to the overall system speed. The 3-state outputs enable bus isolation, preventing signal contention and improving system reliability.

The FCT technology ensures low noise and minimal signal distortion, enhancing data integrity. The device's TSSOP package offers a compact footprint, allowing for efficient use of board space. This latch is often used in data acquisition systems, communication equipment, and other applications requiring fast and reliable data handling. It operates at a 5V supply voltage and is designed to meet the stringent requirements of high-performance digital systems. The latch enable signal controls when the data is latched, providing precise timing control and synchronous operation.
