CY74FCT240TQCT

Overview

The CY74FCT240TQCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight inverting inputs with three-state outputs housed in a QSOP-20 package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 8 ns at 5 V, a high-level output current of -32 mA, and a low-level output current of 64 mA. Static current is specified at 100 nA, with a maximum operating temperature of +85 °C.

Feature Summary

• Provides tri-state control for eight inverting signal paths
• Supports TTL-compatible input levels with CMOS technology
• Delivers high drive capability for bus interfacing applications

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix 'TQCT' against the manufacturer's official datasheet to confirm the QSOP-20 package type and tape-and-reel packaging configuration. Ensure compatibility with moisture sensitivity level requirements during assembly. Cross-reference the part number with the latest Texas Instruments documentation to validate RoHS compliance status and any recent manufacturing changes.

Selection Notes

Select this component when designing systems requiring octal buffering with inversion and high-speed performance. The FCT series offers faster switching speeds compared to standard LS logic while maintaining CMOS power efficiency. Consider the 8 ns propagation delay and 64 mA sink current for driving capacitive loads on data buses or clock lines within the specified 5 V operating range.
