CY74FCT541ATSOCT

Overview

The CY74FCT541ATSOCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting inputs with three-state outputs housed in a 20-pin 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 -32 mA, and low-level output current of 64 mA. Static current is specified at 200 nA, with a maximum operating temperature of +85°C.

Feature Summary

• Provides octal buffering and line driving capabilities with non-inverting signal paths.
• Features tri-state outputs for effective bus management and isolation.
• Designed for CMOS technology ensuring low static power consumption.

Applications

• Memory module addressing and data buffering
• Clock distribution networks
• Bus-oriented architectures requiring high drive capability

Procurement Notes

Verify the specific suffix 'CT' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure the component matches the required RoHS compliance status and lead finish details before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability.

Selection Notes

Select this component when an octal buffer with tri-state control is required for 5V CMOS systems. Consider the 20-SOIC package constraints and the 4.1 ns propagation delay relative to system timing requirements. Evaluate the 64 mA low-level sink capability against load conditions to ensure adequate drive strength for connected buses or memory interfaces.
