CY74FCT541CTQCT

Overview

The CY74FCT541CTQCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting channels with three-state outputs housed in a 20-pin SSOP package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input levels. Key electrical parameters include a propagation delay of 4.8 ns at 5 V, high-level output current of -32 mA, and low-level output current of 64 mA. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides octal buffering and line driving capabilities with non-inverting signal paths.
• Integrates three-state outputs for effective bus management and isolation.
• Supports TTL-compatible input logic levels for broad interface compatibility.

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Multiplexer receivers

Procurement Notes

Verify the specific suffix 'CTQCT' against the manufacturer's official datasheet to confirm the QSOP/SSOP package type and tape-and-reel orientation. Ensure the component meets RoHS compliance requirements as indicated in the latest documentation. Cross-reference the ordering number with authorized distributors to validate authenticity and avoid counterfeit parts.

Selection Notes

Select this component when designing systems requiring high-speed data transfer with low propagation delay. The FCT series offers CMOS power consumption with TTL speed performance. Consider the 20-lead SSOP form factor for space-constrained surface-mount applications. Verify that the required drive strength aligns with the connected load capacitance specifications.

Part Context

This part belongs to the CY74FCT541T family of octal buffers and line drivers. It serves as a standard logic interface solution for transferring data between different circuit blocks. The FCT technology combines the benefits of CMOS low power with Schottky TTL speed, making it suitable for general-purpose digital logic applications requiring reliable signal integrity.

Replacement Considerations

Check for CY74FCT541ATQCT or CY74FCT541CTSOCT as potential alternatives depending on the required package style (SSOP vs SOIC). Verify pinout compatibility and electrical characteristics before substitution.
