CY74FCT2245TQCT

Overview

The CY74FCT2245TQCT is an octal bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features eight non-inverting channels with three-state outputs and integrated series damping resistors. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. Packaged in a 20-pin QSOP, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates series damping resistors for signal integrity
• Provides bidirectional data transfer via eight channels
• Features three-state outputs for bus isolation

Applications

• High-speed data bus architectures
• Memory module interfacing
• Communication system data routing

Procurement Notes

Verify the specific suffix 'TQCT' against official documentation to confirm the presence of series damping resistors and the QSOP-20 package configuration. Ensure compatibility with required operating temperatures and voltage specifications before integration into the design.

Selection Notes

Select this component when bidirectional data transfer requires integrated damping to minimize reflections on high-speed buses. The inclusion of damping resistors distinguishes it from standard variants, making it suitable for applications demanding enhanced signal quality without external components.

Part Context

This part belongs to the CY74FCT2245T family of octal bus transceivers. It shares functional similarities with other FCT series devices but is distinguished by its specific packaging and internal damping resistor integration, catering to specialized high-speed interface requirements.

Replacement Considerations

Substitutes must match the octal bus transceiver function, 20-pin QSOP package, and include series damping resistors. Verify that alternative parts support the same 4.75V to 5.25V supply range and TTL logic levels.
