CY74FCT16827CTPVCT

Overview

The CY74FCT16827CTPVCT is a high-speed CMOS logic device manufactured by Texas Instruments, belonging to the FCT series. It functions as a 20-bit buffer or line driver with three-state outputs. The component is housed in a 56-pin SSOP package and operates within a supply voltage range of 4.5V to 5.5V. It supports an operating temperature range from -40°C to +85°C. The device features non-inverting logic and provides significant drive capability suitable for bus-oriented systems.

Feature Summary

• Provides 20-bit buffering with true output polarity
• Features three-state outputs for bus driving applications
• Operates on standard 5V CMOS logic levels

Applications

• Bus-oriented memory systems
• Clock drivers
• Buffering registers

Procurement Notes

Verify the specific suffix 'CTPVCT' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the source document explicitly lists this part number as active or available, as older revisions may have different packaging or performance specifications. Cross-reference the RoHS status and moisture sensitivity level if required for your assembly process.

Selection Notes

Select this component when a 20-bit wide buffer with three-state control is required for 5V systems. It is suitable for replacing legacy 74FCT827 equivalents in designs needing higher density. Consider the SSOP-56 package constraints regarding thermal dissipation and board space. Verify that the load capacitance and drive strength meet the specific trace requirements of the target application.

Part Context

This device is part of the Texas Instruments FCT (Fast CMOS Technology) family, designed to bridge the speed gap between TTL and standard CMOS logic. The FCT series offers propagation delays comparable to LS-TTL while maintaining CMOS power consumption benefits. The 16827 variant specifically addresses the need for wide data path buffering in complex digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers include CY74FCT16827ATPVC and CY74FCT16827T. These alternatives share the same logical function and pinout but may differ in packaging type or specific electrical parameters such as propagation delay or drive current. Always verify compatibility with the original design specifications before substitution.
