Overview
The CY74FCT240CTQCTE4 is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V. The device provides high drive capability with output currents of -32 mA for high state and 64 mA for low state. It exhibits a propagation delay of 4.8 ns at 5 V. The component is housed in a 20-SSOP package and supports surface-mount installation. It functions as an inverting logic circuit with eight input lines and eight output lines.
Feature Summary
- Octal configuration providing eight independent buffering channels
- Three-state output capability for bus-oriented applications
- High current drive strength supporting direct interface loads
Applications
- Memory address buffering
- Clock driver circuits
- Bus-oriented architectures
Procurement Notes
Verify the specific suffix E4 indicates lead-free compliance and RoHS status against the latest manufacturer documentation. Confirm the 20-SSOP package dimensions match your PCB footprint requirements. Ensure the inverting logic polarity aligns with your system design needs. Check for any moisture sensitivity level restrictions during storage and handling procedures.
Selection Notes
Select this component when an octal inverting buffer with three-state control is required for 5V CMOS systems. Consider the 4.8 ns propagation delay for timing constraints. Evaluate the 20-SSOP package size against available board space. Compare drive current capabilities with other FCT series variants if higher load driving is necessary.
Part Context
This part belongs to the CY74FCT240T family of 8-bit buffers and line drivers. It shares functional similarities with non-inverting counterparts like the CY74FCT241. The E4 suffix typically denotes environmental compliance features such as lead-free terminations. It serves as a standard logic interface solution within Texas Instruments' FCT product line.
Replacement Considerations
Publicly confirmed substitute part numbers are not explicitly listed in the provided source material. Verify compatibility with generic 74FCT240 equivalents only after confirming pinout and electrical parameter alignment.
