CY74FCT245CTQCT

Overview

The CY74FCT245CTQCT is an octal bus transceiver from the FCT logic series manufactured by Texas Instruments. It features eight bidirectional data channels with three-state outputs, enabling efficient data transfer between buses. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. It is housed in a 20-pin Thin Quad Flatpack (TQFP) package designed for surface-mount applications.

Feature Summary

• Provides bidirectional data transmission across eight independent channels
• Features three-state outputs to prevent bus contention during inactive states
• Supports non-inverting logic operation for direct signal routing

Applications

• High-speed data bus architectures requiring bidirectional control
• Memory interface circuits connecting processors to storage modules
• I/O expansion systems utilizing parallel data pathways

Procurement Notes

Verify the specific suffix 'CTQCT' against official Texas Instruments documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with required operating temperatures and voltage levels before integration into final designs.

Selection Notes

Select this component when designing systems that require robust bidirectional data handling with minimal propagation delay. The FCT series offers CMOS performance with TTL compatibility, making it suitable for mixed-logic environments where signal integrity and speed are critical factors.

Part Context

This part belongs to the CY74FCT245 family of octal bus transceivers. It shares functional similarities with other FCT devices but is distinguished by its specific pinout and packaging configuration. The TQFP format facilitates compact PCB layouts while maintaining reliable thermal dissipation characteristics for continuous operation.
