CY74FCT2240ATQCT

Overview

The CY74FCT2240ATQCT is an octal buffer and line driver from the Texas Instruments FCT logic series. It features a 20-pin SSOP package with surface mount installation. The device operates within a supply voltage range of 4.75 V to 5.25 V. It provides non-inverting, three-state outputs with a propagation delay of 6.5 ns at 5 V. The component supports TTL input levels and functions as an octal buffer/line driver.

Feature Summary

• Octal configuration providing eight independent buffering channels
• Three-state output capability for bus-oriented applications
• Compatible with FCT and F Logic families for system integration

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• High-speed data transmission line termination

Procurement Notes

Verify the specific suffix 'TQCT' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the SSOP-20 package dimensions align with the target PCB footprint constraints. Ensure the operating temperature range meets the environmental specifications of the final equipment design.

Selection Notes

Select this component when an octal, non-inverting buffer with three-state control is required for high-speed digital interfaces. The FCT technology offers speed comparable to LS TTL with CMOS power consumption. Consider the 25-ohm internal series resistors for reducing transmission-line reflection noise in signal integrity critical designs.

Part Context

This part belongs to the CY74FCT family, which bridges the performance gap between standard CMOS and bipolar logic. The FCT series is designed for high-speed applications requiring low power dissipation. The CY74FCT2240 variant specifically addresses the need for robust signal buffering in complex digital systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the same FCT family, such as the CY74FCT2240CTQCT, noting any differences in package type or electrical characteristics. Verify functional equivalence if substituting with other octal buffer devices from different manufacturers.
