CY74FCT2240CTQCTE4

Overview

The CY74FCT2240CTQCTE4 is an octal buffer and line driver from the Texas Instruments FCT logic series. It features three-state outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device provides a propagation delay of 4.1 ns at 5 V and supports TTL input levels. It is housed in a QSOP-20 surface-mount package and functions as an inverting buffer with low quiescent current.

Feature Summary

• Octal configuration providing eight independent buffering channels
• Three-state output capability for bus-oriented systems
• Inverting logic function compatible with TTL input standards

Applications

• Memory address buffering
• Clock distribution circuits
• Signal driving applications requiring high speed

Procurement Notes

Verify the specific suffix 'E4' against official documentation to confirm environmental compliance details, such as lead-free status or RoHS certification. Ensure the QSOP-20 package matches design constraints. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when an inverting octal buffer with three-state outputs is required for high-speed digital interfaces. It is suitable for designs needing TTL-compatible inputs and fast propagation delays. Consider the QSOP-20 package size and thermal characteristics during PCB layout planning.

Part Context

This part belongs to the CY74FCT2240T family of CMOS octal buffers. It shares functional compatibility with other FCT series devices but offers specific inverting characteristics. The E4 suffix typically denotes environmental compliance attributes defined by the manufacturer.

Replacement Considerations

Check for direct substitutes within the CY74FCT2240T family. Verify pinout and electrical specifications against alternatives like the CY74FCT2240ATSOCT if package differences exist.
