74LVT240MSA

Overview

The Fairchild Semiconductor 74LVT240MSA is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0V to 3.6V. The device provides high drive capability with output currents of 24mA at both logic high and low states. It utilizes a 20-pin SSOP package for surface-mount installation. The component supports operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent buffering channels
• Three-state outputs enable bus-oriented transmission and memory address driving
• High drive strength supporting 24mA source and sink currents
• Compatible with standard TTL input voltage levels

Applications

• Memory address drivers in computer systems
• Clock signal distribution networks
• Bus-oriented transmitters and receivers
• General-purpose buffering for parallel data lines

Procurement Notes

Verify the specific manufacturer origin, as Fairchild Semiconductor operations were acquired by onsemi. Confirm the exact suffix 'MSA' corresponds to the 20-SSOP package variant. Check current availability status, as older LVT series components may be subject to discontinuation or lifecycle changes. Ensure RoHS compliance documentation matches the production batch requirements for your specific application standards.

Selection Notes

Select this component when an octal buffer with three-state control is required for low-voltage digital interfaces. It is suitable for applications needing moderate drive strength (24mA) rather than the higher currents found in ACT or ABT series devices. Consider the SSOP package constraints regarding thermal dissipation and board space. Verify that the 2.0V to 3.6V operating range aligns with the system's power supply architecture.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage CMOS applications. It serves as a functional equivalent to other octal buffers like the 74ACT240 but operates at lower voltages. The device is commonly used in embedded systems and consumer electronics where power efficiency and bus isolation are critical design factors.

Replacement Considerations

Public confirmed substitute part numbers: 74LVT240MTC, 74LVT240MTDX.
