Overview
The CY74FCT2543TQC is an octal registered bus transceiver manufactured by Texas Instruments, belonging to the FCT logic series. It features a 24-pin SSOP surface-mount package and supports bidirectional data transfer with three-state outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V and maintains TTL-compatible input and output levels. It functions as a non-inverting latch with independent direction control and includes a master control for the latch mechanism. The component is rated for operation in temperatures ranging from -40°C to +85°C.

Procurement Notes
Verify the specific suffix 'Q' against official documentation to confirm it denotes automotive qualification or specific reliability standards. Ensure the SSOP-24 package matches the target PCB footprint. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement specifications.
Selection Notes
Select this component when an octal registered transceiver with bidirectional capability and three-state outputs is required. It is suitable for applications needing TTL-level compatibility and latch functionality. Verify that the operating temperature range and supply voltage requirements align with the system design constraints.
Part Context
This part belongs to the Texas Instruments CY74FCT2543T family of registered bus transceivers. It shares functional similarities with other members like the CY74FCT2543CTSOC but differs in packaging and potential qualification grades. The FCT series is designed for high-speed CMOS applications requiring low power consumption and fast switching speeds.
Replacement Considerations
Check for direct substitutes such as the CY74FCT2543CTSOC or CY74FCT2543ATSOC. Verify pinout compatibility and electrical characteristics before substitution. Ensure any alternative meets the same package and temperature requirements.
