74LVT240MSAX

Overview

The Fairchild Semiconductor 74LVT240MSAX is a low voltage octal buffer and line driver featuring three-state outputs. It operates within the LVT series, utilizing BICMOS technology to support 3.3V logic systems. The device provides inverted output functionality across two functional units, each handling four bits. Packaged in a 20-pin SSOP format, it is designed for high-speed data bus applications requiring robust signal integrity and noise immunity.

Feature Summary

• Octal configuration with dual 4-bit inverters
• Three-state output capability for bus isolation
• Low voltage operation compatible with 3.3V systems

Applications

• High-speed data bus drivers
• Memory module address and data lines
• Clock distribution networks

Procurement Notes

This component is obsolete and no longer manufactured by Fairchild Semiconductor or its successor entities. Verification of current availability requires checking authorized distributors for remaining stock or identifying qualified replacement parts from active production lines. Ensure compatibility with existing system requirements when sourcing alternatives.

Selection Notes

Select this part only if legacy compatibility is mandatory due to existing board designs. For new projects, consider modern equivalents from active manufacturers that offer improved supply chain stability. Verify pinout and electrical characteristics match the original design specifications before substitution.

Part Context

The 74LVT240 belongs to the Low Voltage TTL (LVT) family, bridging older 5V logic standards with emerging 3.3V systems. This specific MSAX variant indicates a tape-and-reel packaging option suitable for automated assembly processes. Its octal structure allows efficient management of wide data paths in digital circuits.

Replacement Considerations

Verify direct pin-compatible substitutes such as the 74LVT240MTCX or equivalent devices from other manufacturers. Confirm that replacement parts maintain identical logical inversion and three-state control signals to ensure seamless integration without hardware modifications.
