CY74FCT2257CTSOC

Overview

The CY74FCT2257CTSOC is a quad 1-of-2 data selector multiplexer from the FCT logic series, manufactured by Texas Instruments. It features four independent multiplexers in a single package, providing efficient signal routing capabilities. The device operates within a supply voltage range of 4.75 V to 5.25 V and exhibits a propagation delay of 6 ns. Designed for surface-mount applications, it utilizes a 16-pin SOIC-Narrow (SOIC-16) package. The component supports an operating temperature range from -40°C to +85°C, ensuring reliability in industrial environments.

Feature Summary

• Integrates four independent 1-of-2 data selectors for compact signal routing
• Provides high-speed performance with low propagation delay characteristics
• Features three-state outputs to facilitate bus-oriented systems

Applications

• Bus-oriented system architectures requiring multiple data paths
• Portable battery-powered equipment due to low power consumption
• Industrial control systems needing reliable signal switching

Procurement Notes

Verify the specific suffix 'CTSO' confirms the SOIC-16 narrow package and tape-and-reel or tube availability as per the manufacturer's current documentation. Confirm RoHS compliance status and moisture sensitivity level requirements before integration into the assembly process. Ensure the ordering part number matches the exact package and packaging quantity needed for production.

Selection Notes

Select this component when a quad multiplexer configuration is required within space-constrained designs. The FCT series offers compatibility with standard CMOS logic levels while providing faster switching speeds than older families. Consider the 16-pin SOIC package for ease of automated placement and thermal management in dense PCB layouts.

Part Context

This part belongs to the CY74FCT2257T family of high-speed CMOS logic devices. The FCT series is engineered for high-performance digital applications, combining the speed of Schottky TTL with the low power consumption of CMOS technology. It serves as a direct replacement for legacy 74FCT equivalents in existing designs.

Replacement Considerations

Check for pin-compatible alternatives within the same FCT multiplexer family. Verify that any substitute maintains the same 16-pin SOIC package and electrical specifications, particularly the 6 ns propagation delay and 3-state output functionality.
