CY74FCT16646TPVC

Overview

The CY74FCT16646TPVC is a registered bus transceiver manufactured by Texas Instruments. It features two independent circuits, each handling eight bits for a total of 16-bit data width. The device utilizes a 56-pin SSOP package and operates within a supply voltage range of 4.5 V to 5.5 V. It provides three-state outputs with low-level output current of 64 mA and high-level output current of -32 mA. Propagation delay is specified at 6.3 ns. The component supports TTL input and output levels and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates registered bus transceiver functionality with dual independent control channels.
• Provides high-drive three-state outputs suitable for direct interface with system buses.
• Supports non-inverting data transfer with TTL-compatible logic levels.

Applications

• High-performance 16-bit memory register interfaces
• Bus-oriented data transmission systems
• Clocking and buffering applications in industrial environments

Procurement Notes

Verify the specific suffix 'A' or absence thereof against official datasheets, as variants may exist. Confirm the package type matches the required footprint. Check for end-of-life status or obsolescence notices from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when a 16-bit registered transceiver with high drive capability is required. Ensure the design accommodates the 56-pin SSOP form factor. Verify that the system power supply remains within the 4.5 V to 5.5 V range and that thermal management supports the specified operating temperature limits.
