CD74FCT2541TQM

Overview

The CD74FCT2541TQM is an octal buffer and line driver manufactured by Harris Corporation, belonging to the FCT logic series. It features a single element with eight bits per element and provides three-state outputs in a 20-SSOP package. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to 85°C. Output drive capabilities include 15mA for high state and 64mA for low state currents. The component is surface-mount type and is identified as non-compliant with RoHS standards.

Feature Summary

• Provides octal buffering and line driving functions with true output polarity
• Features three-state outputs controlled by active-low enable signals
• Designed for high-speed CMOS technology applications

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• High-performance register banks

Procurement Notes

Verify RoHS compliance status as the component is listed as non-compliant. Confirm the specific manufacturer source, as Harris Corporation assets have been acquired by other entities such as Texas Instruments or Renesas. Ensure the 20-SSOP package dimensions match the design footprint requirements before procurement.

Selection Notes

Select this component for designs requiring octal bus driving with high current sink capability. Compare against similar FCT series devices like the CD74FCT244ATM if non-inverting outputs are preferred. Verify that the 5V supply voltage aligns with the system power rails and that the -40°C to 85°C temperature range meets environmental specifications.

Part Context

This part belongs to the Harris Corporation FCT (Fast CMOS) family, which bridges the performance gap between standard TTL and advanced CMOS technologies. The CD74FCT2541TQM specifically serves as an octal buffer, offering improved switching speeds and lower power consumption compared to older HCT counterparts while maintaining compatible pinouts.

Replacement Considerations

Check for equivalents from Texas Instruments, such as the CY74FCT2541ATSOCG4, which shares the same logical function and package type. Verify pin compatibility and electrical characteristics before substitution.
