CY74FCT157CTQC

Overview

The CY74FCT157CTQC is a quad 2-input multiplexer belonging to the FCT logic series, manufactured by Texas Instruments. It features four independent data selectors with three-state outputs in a 16-pin SSOP package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range from -40°C to +85°C. Propagation delay is specified at 4.3 ns at 5 V, with a maximum power dissipation of 600 mW.

Feature Summary

• Integrates four independent 2-to-1 data selectors with common select lines for efficient signal routing.
• Provides three-state outputs to facilitate bus-oriented architectures and system interconnects.
• Utilizes Fast CMOS (FCT) technology to deliver high-speed switching performance with low power consumption.

Applications

• Bus-oriented systems requiring multiple data path selections
• Portable battery-operated equipment due to low power characteristics
• High-speed data routing in industrial control applications

Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by Texas Instruments despite the Cypress Semiconductor Corp brand association in some databases. Confirm the specific suffix 'CTQC' corresponds to the SSOP-16 package and tape-and-reel shipping format. Ensure compliance with RoHS directives and check for moisture sensitivity levels prior to surface mount assembly processes.

Selection Notes

Select this component when designing circuits that require multiple independent 2-input selection functions within a single integrated circuit. The FCT series offers superior speed compared to standard CMOS logic while maintaining lower power usage than bipolar alternatives. Consider the SSOP-16 package constraints and thermal dissipation requirements relative to the 600 mW limit during PCB layout planning.

Part Context

This part belongs to the CY74FCT157T family of multiplexers. It shares functional similarities with other FCT series logic devices but is distinct in its quad 2-input configuration. The component represents a transition between older CMOS technologies and faster FCT standards, often used in legacy system upgrades or cost-sensitive high-performance designs.

Replacement Considerations

Direct substitutes include CY74FCT157CTD and CY74FCT157CTQCT. Verify pin compatibility and electrical specifications before substitution. Note that package variations such as SOIC-Narrow-16 may require mechanical adaptation.
