CY74FCT157ATDR

Overview

The CY74FCT157ATDR 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 an SOIC-16 package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 4.3 ns at 5 V. It functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides four independent 2-to-1 data selection paths
• Features three-state outputs for bus-driven applications
• Compatible with TTL input levels

Applications

• Data routing in digital systems
• Signal selection in instrumentation
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix 'A' and 'D' against official documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements and signal integrity standards before integration. Confirm moisture sensitivity handling procedures are followed during assembly.

Selection Notes

Select this component when multiple independent 2-input selection paths are required in a compact surface-mount format. Consider the FCT series characteristics for high-speed operation and TTL compatibility. Evaluate board space constraints against the SOIC-16 footprint availability.

Part Context

This part belongs to the CY74FCT157T series of multiplexers. It shares functional similarities with other FCT family devices but offers specific pinout and performance characteristics tailored for quad 2-input applications. It complements other logic components in complex digital designs.

Replacement Considerations

Check for direct substitutes like CY74FCT157CTQCT or CY74FCT157CTD if package variations are acceptable. Verify electrical parameters and pin configurations match exactly before substitution.
