IDT74FCT240TQ

Overview

The IDT74FCT240TQ is an octal buffer and line driver manufactured by Integrated Device Technology. It utilizes advanced dual-metal CMOS technology to provide high-speed signal buffering. The device features two functional blocks, each handling four bits of data with inverted output polarity. It supports a standard operating voltage range and includes three-state outputs for bus-oriented memory and circuit applications. The component is designed to meet JEDEC standards and offers low input leakage current.

Feature Summary

• High drive capability with strong output sourcing and sinking characteristics
• True TTL input and output compatibility for direct interface with logic systems
• Three-state outputs enable efficient bus-oriented architecture management
• Low power consumption typical of CMOS technology

Applications

• Bus-oriented memory architectures
• Clock drivers and buffering
• Memory register drives
• Capacitive loading termination

Procurement Notes

Verify the specific suffix 'Q' against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure the component matches the required RoHS compliance status if applicable to your project specifications. Cross-reference the ordering code with the latest Renesas or IDT documentation to avoid obsolete variants.

Selection Notes

Select this component when an octal buffer with inverted outputs is required for high-speed digital interfaces. It is suitable for designs needing strong drive strength and low power dissipation. Compare propagation delay specifications against system timing requirements. Ensure the package style fits the available PCB footprint constraints.

Part Context

This part belongs to the 74FCT logic family, which bridges the performance gap between standard TTL and CMOS technologies. The FCT series is known for its speed and compatibility with 5V and 3.3V systems. IDT, now part of Renesas, produces these components for industrial and commercial applications requiring reliable signal integrity.

Replacement Considerations

Check for equivalents such as the CY74FCT240 from Texas Instruments or the 74FCT240 from other manufacturers. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement part supports the same inverted output configuration and three-state control logic.
