Overview
The CY74FCT2240TSOCTE4 is an octal buffer and line driver manufactured by Texas Instruments. It belongs to the FCT logic series and features inverting polarity with three-state outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. It provides a maximum low-level output current of 12 mA and a high-level output current of -15 mA. The propagation delay is specified at 6.5 ns at 5 V under a 50 pF load. The component is housed in a 20-pin SOIC package for surface mount installation.
Feature Summary
- Octal configuration providing eight independent inverting buffer channels
- Three-state output capability for bus-oriented systems
- TTL-compatible input and output voltage levels
Applications
- Bus-oriented memory and address drivers
- Clock drivers and buffer circuits
- Multiplexer and demultiplexer data routing
Procurement Notes
Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type matches the required PCB footprint, specifically the 20-SOIC variant. Ensure the inverting logic function aligns with the circuit design requirements before procurement.
Selection Notes
Select this component when an octal inverting buffer with three-state outputs is required. It is suitable for applications needing TTL compatibility and moderate drive strength. Consider the 6.5 ns propagation delay for timing constraints. Verify that the 5V operating voltage range fits the system power supply specifications.
Part Context
This part is part of the CY74FCT2240 family, which includes non-inverting variants like the CY74FCT2240T. The 'E4' suffix typically denotes environmental compliance. It serves as a digital logic interface component within the broader Texas Instruments FCT series of high-speed CMOS logic devices.
Replacement Considerations
The CY74FCT2240T is a related non-inverting variant within the same series. For direct replacement, verify if the inverting function is critical or if a non-inverting buffer suffices. Other FCT series buffers may require logic inversion adjustments in the design.
