74LVT240SJ

Overview

The Fairchild Semiconductor 74LVT240SJ is an octal buffer and line driver featuring inverting 3-STATE outputs. Designed for low-voltage applications, it operates within a supply voltage range of 2.7V to 3.6V. The device utilizes advanced BiCMOS technology to achieve high-speed performance comparable to 5V ABT devices while maintaining low power dissipation. It includes buffered clock and output enable controls common to all channels, facilitating bus-oriented transmission and reception.

Feature Summary

• Octal configuration with inverting 3-STATE outputs for efficient bus management
• Advanced BiCMOS fabrication ensuring high speed and low power consumption
• Compatible with 5V TTL environments despite low-voltage operation
• Glitch-free bus loading during power-up and power-down states

Applications

• Memory address drivers
• Clock drivers
• Bus oriented transmitters or receivers

Procurement Notes

Verify the specific suffix SJ against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the ordering information with current onsemi documentation, as Fairchild Semiconductor operations have been integrated into onsemi.

Selection Notes

Select this component when designing systems requiring octal buffering with low voltage compatibility. It serves as a suitable replacement for older LS-TTL designs where power reduction is necessary without sacrificing drive capability. Consider the 3-STATE output feature for multiplexed bus architectures.

Part Context

This part belongs to the 74LVT logic family, which bridges the gap between standard CMOS and high-speed bipolar technologies. The LVT series is characterized by its ability to interface directly with 5V systems while operating at lower voltages, making it versatile for mixed-voltage digital circuits.

Replacement Considerations

Check for equivalents such as the MM74HCT240MTC for higher drive current needs or the 74ACT240 for faster switching speeds. Verify pinout compatibility before substituting with other octal buffer ICs from different manufacturers.
