CY74FCT157CTSOCT

Overview

The CY74FCT157CTSOCT is a quad 2-input multiplexer from the FCT logic series, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features a propagation delay of 4.3 ns at 5 V. The device supports three-state outputs and is housed in a 16-pin SOIC-Narrow package. Designed for surface mount installation, it functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent 2-to-1 data selectors within a single integrated circuit
• Provides high-speed signal routing with specified low propagation delay characteristics
• Supports three-state output configuration for effective bus line management

Applications

• Data selector circuits requiring multiple input channels
• Bus-oriented switching applications
• High-speed digital signal routing systems

Procurement Notes

Verify the specific suffix 'SOCT' against official datasheets to confirm the tape-and-reel packaging format and moisture sensitivity level. Ensure the order quantity aligns with standard reel specifications. Confirm RoHS compliance status through current manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when designing systems requiring four independent multiplexing paths with fast switching speeds. The FCT series offers CMOS performance with TTL-compatible inputs. Verify that the system power supply remains strictly within the 4.75 V to 5.25 V range to ensure correct logic levels and timing parameters.

Part Context

This part belongs to the CY74FCT157T family of multiplexers. It serves as a high-performance alternative to older logic families, offering improved speed and lower power consumption while maintaining compatibility with standard digital interfaces. The device is widely used in industrial and commercial electronic equipment.

Replacement Considerations

Check for direct pin-compatible substitutes within the same FCT family, such as other CY74FCT157 variants with different packaging options like tube or QFN formats. Ensure any replacement maintains the same 16-pin SOIC footprint and electrical specifications.
