CY74FCT399CTSOCT

Overview

The CY74FCT399CTSOCT is a quad multiplexer from the FCT logic series, manufactured by Texas Instruments. It features four independent 2-to-1 data selectors housed in a 16-pin SOIC package. The device operates on a single power supply ranging from 4.75 V to 5.25 V. It exhibits a propagation delay of 6.1 ns at 5 V and supports surface mount installation. The component functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent 2-input multiplexers into a single integrated circuit
• Provides high-speed signal routing with low propagation delay characteristics
• Supports standard surface mount technology for automated assembly processes

Applications

• Data selection circuits requiring multiple input channels
• Signal routing in digital communication systems
• Bus architecture management in embedded controllers

Procurement Notes

Verify manufacturer designation as Texas Instruments despite historical Cypress branding. Confirm RoHS compliance status through official documentation. Check current availability as distribution records indicate discontinuation or limited stock. Ensure package type matches SOIC-16 specifications for PCB footprint compatibility.

Selection Notes

Select this component for applications requiring compact quad multiplexing solutions. Verify voltage requirements align with the 4.75 V to 5.25 V operational range. Consider thermal performance within the specified industrial temperature limits. Evaluate pin compatibility against existing SOIC-16 layouts during design integration.
