74LVT240MTCX

Overview

The Fairchild Semiconductor 74LVT240MTCX is an octal buffer and line driver featuring inverted outputs with three-state capability. It operates within a supply voltage range of 2.7V to 3.6V and utilizes a 20-pin TSSOP surface-mount package. The device provides high drive currents, specified at 32mA for high-level output and 64mA for low-level output. It is designed for low-voltage applications while maintaining compatibility with standard logic levels.

Feature Summary

• Octal configuration providing eight independent buffering channels
• Three-state output control for efficient bus management
• Inverted logic function for signal inversion applications
• High current drive capability supporting direct interface loads

Applications

• Clock drivers and clock buffers in digital systems
• Bus-oriented memory and address drivers
• Capacitive loading driving and bus recovery circuits
• Multiplexer transceiver applications

Procurement Notes

Verify the manufacturer origin as the part number prefix may vary between Fairchild Semiconductor and onsemi due to corporate acquisition history. Confirm the specific suffix indicates the correct tape-and-reel or cut-tape packaging variant required for assembly. Ensure RoHS compliance status matches current environmental regulations for the intended deployment region.

Selection Notes

Select this component when an octal buffer with inverted outputs and three-state control is required for 3.3V logic systems. The high drive current specifications make it suitable for driving heavy capacitive loads or long buses. Verify that the 20-lead TSSOP package dimensions fit the available PCB footprint and thermal requirements of the design.

Part Context

This component belongs to the 74LVT logic family, which is optimized for low-voltage operation. It serves as a standard interface solution for connecting 3.3V microprocessors and memory devices. The device replaces older higher-voltage logic families in modern portable and battery-operated electronic equipment designs.

Replacement Considerations

Direct substitutes include SN74LVT240ADBR from Texas Instruments. Verify pinout compatibility and electrical characteristics before substitution.
