CD74FCT541DTM

Overview

The CD74FCT541DTM is an inverting bus driver from the FCT series, manufactured by Harris Corporation. It features a single function with eight bits per element and provides three-state outputs. The device operates within a supply voltage range of 4.75V to 5.25V. It is housed in a 20-SOIC package with a width of 0.295 inches (7.50mm). The component is designed for surface mount installation and supports dual output enable control.

Feature Summary

• Inverting buffer functionality with eight-bit parallel data handling
• Three-state output capability for bus line isolation
• Dual output enable control mechanism

Applications

• Parallel data bus buffering
• Signal inversion in digital logic circuits
• Memory address/data bus drivers

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successors, noting that legacy parts may be sourced through distributors like Rochester Electronics. Confirm the specific suffix 'DTM' corresponds to the 20-SOIC package and operating specifications. Check RoHS compliance status, as older Harris logic families often lack modern environmental certifications. Ensure the source document explicitly lists this part number to avoid confusion with similar variants.

Selection Notes

Select this component when an inverting eight-bit bus driver with three-state outputs is required for 5V logic systems. The FCT series offers fast switching speeds suitable for high-performance applications. Consider the 20-SOIC package constraints for PCB layout. Verify that the supply voltage requirements align with the 4.75V to 5.25V specification before integration into the design.

Part Context

This component belongs to the Harris Corporation FCT logic family, which utilizes Fast CMOS technology. The 74FCT541 is a standard industry designation for an inverting octal bus transceiver. Harris Corporation was a significant producer of such logic ICs before its semiconductor assets were acquired by other entities, leading to complex sourcing channels for original equipment manufacturer parts.

Replacement Considerations
