CY74FCT2257CTQCT

Overview

The CY74FCT2257CTQCT is a quad multiplexer from the FCT logic series, manufactured by Texas Instruments. It features four independent 1-of-2 data selectors housed in an SSOP-16 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 5 ns at 5 V and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent 1-of-2 data selectors for parallel signal routing
• Provides high-speed switching with low propagation delay characteristics
• Compatible with standard TTL input levels for broad interface support

Applications

• Data selection and routing in digital logic circuits
• Signal path configuration in embedded systems
• Multiplexing applications requiring fast switching speeds

Procurement Notes

Verify the specific suffix 'CTQCT' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging and moisture sensitivity classification. Ensure the ordering part number matches the required package variant and environmental compliance standards before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring multiple independent 2-to-1 multiplexing channels within a compact footprint. It is suitable for applications demanding compatibility with FCT logic families and operation under standard 5V power supplies with defined industrial temperature constraints.

Part Context

This component belongs to the CY74FCT2257T series, which groups quad multiplexers with similar functional architectures. It shares the FCT logic family characteristics, ensuring interoperability with other devices in the same series while offering distinct packaging options like the SSOP-16 form factor for space-constrained designs.

Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers within the same series or compatible logic families. Verify pinout compatibility and electrical specifications before substituting.
