74FCT16501NATPA

Universal Bus Functions Overview

The 74FCT16501NATPA is an 18-bit registered bus transceiver from the FCT series by IDT. It features a 56-pin TVSOP package and supports bidirectional data transfer with independent output enable control for each direction. The device operates within a temperature range of -40 °C to 85 °C, utilizes CMOS technology, and provides true output polarity with three-state outputs. It is designed for high-speed applications requiring registered data latching capabilities.

Universal Bus Functions Feature Summary

• Provides 18-bit registered bus transceiver functionality for high-speed data handling
• Features independent output enable control for each direction to manage data flow
• Supports bidirectional data transfer with true output polarity and three-state outputs

Universal Bus Functions Applications

• High-speed data bus interfaces in computing systems
• Memory buffer applications requiring registered data storage
• Industrial control systems needing reliable bidirectional communication

Universal Bus Functions Procurement Notes

Verify the specific suffix 'NATPA' against official IDT documentation to confirm package type and lead-free status. Ensure compatibility with existing PCB footprints for the 56-pin TVSOP configuration. Check for RoHS compliance requirements as some variants may not meet current environmental standards. Confirm operating temperature ranges match system specifications.

Universal Bus Functions Selection Notes

Select this component when 18-bit width and registered buffering are required for bus transceivers. Consider the FCT series speed characteristics and CMOS power consumption. Evaluate the 56-pin TVSOP package constraints against board space limitations. Compare with other FCT variants if different bit widths or unregistered options are suitable for the design.

Universal Bus Functions Part Context

This part belongs to the IDT FCT (Fast CMOS) logic family, known for high-speed performance comparable to LS-TTL but with CMOS power efficiency. The 74FCT16501 series specifically addresses applications needing wide data paths with internal registration. IDT, now part of Renesas, has historically supplied these components for telecommunications and computer peripheral interfaces.

Universal Bus Functions Replacement Considerations

Check for direct pin-compatible substitutes within the same FCT family, such as the 74FCT16500 series, which may offer similar functionality with minor electrical differences. Verify that any replacement maintains the 18-bit width and registered bus transceiver architecture. Ensure the alternative component supports the same 56-pin TVSOP package and operating temperature range.
