CY74FCT2240TS0C

Overview

The CY74FCT2240TS0C is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74FCT logic series. It features eight inverting channels with three-state outputs housed in a 20-SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 4.1 ns at 5 V, high-level output current of -15 mA, low-level output current of 12 mA, and quiescent current of 200 nA. It supports surface-mount installation and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Provides octal buffering and driving capabilities for signal integrity maintenance.
• Features three-state outputs to facilitate bus-oriented architectures.
• Delivers high-speed performance suitable for demanding timing requirements.

Applications

• Clock distribution networks
• Memory buffer interfaces
• Data bus drivers

Procurement Notes

Verify the specific suffix 'TS0C' against official datasheets to confirm pinout and electrical characteristics match project requirements. Ensure the component source is authorized to guarantee authenticity. Confirm RoHS compliance status as indicated in the manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when an octal inverting buffer with three-state control is required for 5V CMOS systems. Consider the 4.1 ns propagation delay for speed constraints and the 20-SOIC package for PCB layout compatibility. Evaluate the low quiescent current benefit for power-sensitive designs compared to standard TTL alternatives.

Part Context

This part belongs to the Texas Instruments 74FCT family, which bridges Fast CMOS and Fast TTL technologies. It offers improved switching speeds and lower power consumption than legacy counterparts while maintaining compatible drive levels. The octal configuration allows for efficient handling of wide data buses in complex digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative octal buffers such as the CY74FCT2244T if non-inverting functionality is acceptable, noting the polarity difference.
