CY74FCT2245CTSOCG4

Overview

The CY74FCT2245CTSOCG4 is an octal bus transceiver from the Texas Instruments FCT logic series. It operates within a supply voltage range of 4.75 V to 5.25 V and features TTL-compatible input and output levels. The device provides tri-state outputs with a propagation delay of 7 ns. It supports low-level output currents of 12 mA and high-level output currents of -15 mA. Packaged in a 20-SOIC format, it functions as a non-inverting buffer suitable for surface-mount applications across temperatures from -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent bidirectional data paths
• Tri-state outputs enabling effective bus line management
• TTL-compatible input and output voltage thresholds

Applications

• High-performance memory mapping systems
• Clock drivers and buffering
• Bus-oriented communications

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free construction when sourcing. Confirm the package designation matches the required SOIC-20 footprint for PCB layout compatibility. Ensure the operating temperature range aligns with the intended environmental conditions of the final assembly.

Selection Notes

Select this component for designs requiring fast switching speeds and robust drive capability on parallel buses. The FCT series offers improved performance over standard LS logic while maintaining pinout compatibility. Consider the 20-pin SOIC package constraints regarding thermal dissipation and board space availability during integration.

Part Context

This part belongs to the broader 74FCT family of high-speed CMOS logic devices manufactured by Texas Instruments. It serves as a variant within the octal bus transceiver category, distinguished by its specific packaging and compliance markings. The device complements other FCT components used in complex digital signal processing architectures.

Replacement Considerations

Cross-reference with CY74FCT2245TSOC or CY74FCT2245ATSOC for functional equivalents. Verify that alternative manufacturers offer identical pin configurations and electrical characteristics to ensure seamless substitution without circuit redesign.
