CY74FCT157ATSOCT

Overview

The CY74FCT157ATSOCT is a quad 2-input multiplexer from the FCT logic series, manufactured by Texas Instruments. It features four independent data selectors with three-state outputs in a 16-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports propagation delays of 4.3 ns at 5 V. It functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent 2-to-1 data selectors for efficient signal routing
• Provides three-state outputs to facilitate bus-oriented systems
• Compatible with TTL input levels for direct interface with digital logic

Applications

• Bus-oriented memory addressing systems
• Signal path selection in data acquisition circuits
• Data routing in telecommunications equipment

Procurement Notes

Verify the specific suffix 'TSOCT' against official datasheets to confirm the tape-and-reel packaging configuration and moisture sensitivity level. Ensure the component matches the required operating temperature range and voltage specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when a compact solution for multiple parallel data paths is required. The FCT series offers high-speed performance suitable for modern digital designs. Consider the 16-pin SOIC footprint for PCB layout compatibility and verify that the three-state output capability aligns with the system's bus architecture requirements.

Part Context

This part belongs to the CY74FCT157T family of multiplexers. It serves as a high-speed alternative to legacy logic families, providing improved switching speeds while maintaining standard logic compatibility. The device is designed for applications requiring reliable data selection in complex digital systems.

Replacement Considerations

Check for pin-compatible alternatives within the same FCT family or equivalent parts from other manufacturers. Verify that any substitute maintains the same voltage range, speed characteristics, and package dimensions to ensure seamless integration without redesigning the circuit board.
