CY74FCT240CTSOC

Overview

The CY74FCT240CTSOC is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features inverting polarity and provides three-state outputs for effective bus management. The device operates within a supply voltage range of 4.75 V to 5.25 V and utilizes CMOS technology. It is housed in a 20-pin SOIC package with surface mount installation. Key electrical characteristics include a high-level output current of -32 mA and a low-level output current of 64 mA. The propagation delay is specified at 5.2 ns, with a maximum operating temperature of +85°C.

Feature Summary

• Provides eight independent buffering channels with inverted signal polarity for precise data direction control.
• Integrates three-state output capability to facilitate efficient bus-oriented architectures and system isolation.
• Utilizes advanced CMOS construction to achieve low static power consumption while maintaining high-speed performance.

Applications

• Bus-oriented systems requiring signal buffering and direction control
• Clock drivers and timing buffer circuits
• Memory module address and data line drivers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure storage conditions adhere to humidity requirements to prevent package degradation. Cross-reference ordering suffixes to match specific packaging formats such as tube quantities. Validate that the procurement source guarantees traceability for quality assurance purposes.

Selection Notes

Select this component when designing systems requiring octal buffering with active-low inversion characteristics. Consider the 5.2 ns propagation delay for timing-critical applications within the specified voltage range. Evaluate the 20-SOIC package dimensions against available PCB real estate constraints. Compare output drive strengths against load requirements to ensure signal integrity across the bus structure.

Part Context

This part belongs to the broader CY74FCT240T family of octal buffers. Variants within this series may differ in speed grades, such as the CY74FCT240ATSOCT which offers faster switching speeds. The standard CY74FCT240CTSOC represents a specific performance tier within the FCT logic portfolio designed for general-purpose digital interfacing tasks.

Replacement Considerations

The CY74FCT240ATSOCT serves as a verified substitute offering similar functionality with potentially different speed characteristics. Other compatible options within the same logic family should be evaluated based on pin compatibility and electrical specifications.
