CY74FCT157CTQCT

Overview

The CY74FCT157CTQCT is a quad multiplexer from the FCT logic series, manufactured by Texas Instruments. It features four independent 2-input data selectors with three-state outputs in an SSOP-16 package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports surface mount installation. Key electrical parameters include a propagation delay of 4.3 ns at 5 V, a maximum power dissipation of 600 mW, and an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent 2-input multiplexers with shared select lines for efficient data routing
• Provides three-state outputs to facilitate bus-oriented systems and signal isolation
• Utilizes CMOS technology to achieve low static power consumption and high-speed switching performance

Applications

• Bus-oriented system architectures requiring multiple data path selection
• Data routing applications in industrial control environments
• Communication equipment utilizing standard TTL-compatible logic levels

Procurement Notes

Verify the specific suffix 'QCT' against official datasheets to confirm the SSOP-16 package and reel packaging configuration. Ensure compliance with humidity sensitivity classifications and lead-free manufacturing standards required for your assembly process before finalizing orders.

Selection Notes

Select this component when designing circuits that require four separate 2-to-1 data paths with tri-state capability. It is suitable for applications demanding fast propagation delays and compatibility with standard 5V logic families. Consider the SSOP-16 footprint constraints during PCB layout planning.

Part Context

This part belongs to the CY74FCT157T series of multiplexers. It shares functional similarities with other FCT family devices but is distinct in its quad configuration and specific output drive characteristics. The QCT suffix denotes the specific tape-and-reel packaging variant offered by the manufacturer.

Replacement Considerations

Consult official substitution guides for equivalent quad multiplexers within the FCT or similar high-speed logic families. Verify pinout compatibility and electrical specifications before replacing the original component.
