CY74FCT157CTD

Overview

The CY74FCT157CTD is a quad multiplexer from the FCT logic series, manufactured by Texas Instruments. It features four independent 2-input data selectors housed in a 16-pin SOIC-Narrow package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports surface-mount installation. It exhibits a propagation delay of 4.3 ns at 5 V and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent 2-input multiplexers for parallel data selection
• Provides high-speed signal routing with low propagation delay characteristics
• Supports standard surface-mount assembly techniques for compact circuit design

Applications

• Data selector circuits requiring multiple input channels
• Signal routing in digital communication systems
• Logic interface modules in industrial control equipment

Procurement Notes

Verify the specific suffix 'TD' corresponds to the SOIC-16 narrow package and tube packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the ordering part number matches the exact speed grade and temperature rating required for the target application environment before finalizing procurement.

Selection Notes

Select this component when designing systems requiring four separate 2-to-1 data paths. The FCT series offers CMOS compatibility with TTL-level inputs. Consider the 16-pin footprint constraints and thermal management requirements for the specified operating temperature range during PCB layout planning.

Part Context

This device belongs to the CY74FCT157T family of multiplexers. It serves as a high-performance alternative to legacy logic families, providing faster switching speeds while maintaining electrical compatibility with standard transistor-transistor logic interfaces. The component is widely used in general-purpose digital logic applications.

Replacement Considerations

Compatible substitutes include other variants within the CY74FCT157T family, such as CY74FCT157CTQCT (SSOP-16) or CY74FCT157C (PDIP-16), provided the pinout and electrical specifications remain identical.
