CY74FCT2257CTQC

Overview

The CY74FCT2257CTQC is a quad 1-of-2 data selector multiplexer from the FCT logic series, manufactured by Texas Instruments. It integrates four independent multiplexers within a single SSOP-16 package. The device operates with a supply voltage range of 4.75 V to 5.25 V and supports a maximum propagation delay of 5 ns at 5 V. It functions within an industrial temperature range of -40°C to +85°C and features TTL-compatible input levels.

Feature Summary

• Integrates four independent 1-of-2 data selectors in a compact surface-mount package
• Provides TTL-compatible input thresholds for direct interfacing with standard logic families
• Delivers high-speed signal routing with low propagation delay characteristics

Applications

• Data routing in digital communication systems
• Signal selection in microprocessor-based control circuits
• Address decoding and bus switching applications

Procurement Notes

Verify the specific suffix 'CTQC' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the ordering part number matches the required pinout and electrical specifications precisely before procurement.

Selection Notes

Select this component when a design requires multiple independent signal paths controlled by separate select lines. The FCT series offers faster switching speeds compared to standard CMOS alternatives while maintaining compatibility with TTL logic levels, making it suitable for high-performance digital interfaces.

Part Context

This multiplexer belongs to the CY74FCT family, which utilizes Fast CMOS technology to achieve performance comparable to transistor-transistor logic (TTL) but with lower power consumption. The FCT series is widely used in embedded systems requiring reliable data path management and fast signal integrity across various industrial and commercial environments.
