Overview
The CY74FCT646TQCTE4 is an octal bus transceiver with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.75V to 5.25V and supports TTL input and output levels. The device features low-level output current of 64mA and high-level output current of -32mA. It has a propagation delay of 9ns and functions as a non-inverting registered bus transceiver. The component is housed in a 24-SOIC package, suitable for surface mount installation.
Feature Summary
- Octal bus transceiver functionality with registered data storage
- Three-state outputs for efficient bus line driving
- Compatible with TTL logic input and output voltage levels
Applications
- High-speed data bus systems requiring registered buffering
- Memory module interfacing in computer architectures
- Industrial control systems utilizing parallel data transmission
Procurement Notes
Verify the specific suffix E4 indicates RoHS compliance when sourcing. Confirm package type matches design requirements. Check manufacturer status as this series may be discontinued or superseded. Ensure environmental certifications align with project regulations before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring octal data transfer with registration capabilities. Consider the 24-SOIC package size for PCB layout constraints. Evaluate the 9ns propagation delay against system timing requirements. Verify power supply stability within the specified 4.75V to 5.25V range for optimal performance.
Part Context
This part belongs to the Texas Instruments 74FCT logic family, designed for fast CMOS technology applications. It serves as a registered transceiver variant within the broader FCT series, providing enhanced data integrity through internal latching mechanisms compared to standard unregistered bus transceivers.
Replacement Considerations
The CY74FCT646ATQCT is listed as a similar substitute option. Verify pin compatibility and electrical specifications before substitution. Check availability and lead times for alternative packages if the original is obsolete.
