CY74FCT541ATPC

Overview

The CY74FCT541ATPC is an octal buffer and line driver manufactured by Texas Instruments. It features eight non-inverting buffers with three-state outputs, designed for high-speed data bus applications. The device operates within a supply voltage range of 4.75V to 5.25V and supports TTL input levels. It is housed in a 20-pin PDIP package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides eight non-inverting buffer channels with three-state output capability for efficient bus management.
• Supports TTL-compatible input logic levels for seamless integration with standard digital systems.
• Operates within a standard 5V power supply range to ensure compatibility with legacy and modern logic families.

Applications

• High-speed data bus buffering
• Memory address decoding
• Clock distribution circuits

Procurement Notes

Verify the specific package type and temperature grade against project requirements before ordering. Confirm that the manufacturer designation aligns with current production status, as component sourcing may involve multiple authorized distributors. Ensure compliance with relevant environmental standards such as RoHS when integrating into final assemblies.

Selection Notes

Select this component for applications requiring robust signal buffering with high drive capability. The three-state feature allows multiple devices to share a common bus without interference. Consider the PDIP package for through-hole prototyping or environments where surface-mount options are unsuitable.

Part Context

This part belongs to the 74FCT logic family, known for CMOS performance with TTL compatibility. It serves as a fundamental building block for digital logic designs requiring reliable signal transmission and isolation between different circuit sections.

Replacement Considerations

Check for direct pin-to-pin replacements within the same FCT series, such as other variants in the 74FCT541 family, ensuring identical package and electrical specifications.
