MC74LVX240MG

Overview

The MC74LVX240MG is an 8-bit inverting buffer and line driver manufactured by onsemi. It belongs to the LVX logic series, designed for low-voltage CMOS applications with a supply voltage range of 2 V to 3.6 V. The device features three-state outputs, allowing multiple drivers to share a bus without interference. It is housed in a 20-lead SOEIAJ package (also referred to as TSSOP or SOIC-Wide depending on specific footprint variations) suitable for surface mount technology. The component operates within an industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides eight-bit inverting buffering with high-speed signal transmission capabilities
• Features three-state outputs to facilitate bus-oriented systems and data communication
• Operates efficiently at low supply voltages ranging from 2 V to 3.6 V

Applications

• Bus-oriented systems requiring signal isolation and driving
• Data communication circuits needing level shifting or buffering
• Microprocessor-based systems utilizing low-voltage logic interfaces

Procurement Notes

Verify the exact package marking and lead configuration against the datasheet, as SOEIAJ-20 may have specific footprint requirements distinct from standard SOIC-20. Confirm that the operating voltage environment strictly remains within the 2 V to 3.6 V limit to ensure reliability. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure thermal management supports the industrial temperature grade up to 125°C during operation.

Selection Notes

Select this component when designing low-voltage digital systems requiring eight-channel inverting buffers with tri-state control. It is suitable for replacing older HC or HCT series devices where lower power consumption and reduced supply voltage are necessary. Consider the propagation delay characteristics relative to your system clock speed. Ensure the PCB layout accommodates the specific pinout of the 20-lead thin-shrink small-outline package.

Part Context

This part is part of onsemi's LVX family of low-voltage CMOS logic devices. The LVX series is optimized for portable and battery-powered applications due to its wide operating voltage range and low power consumption. It serves as a bridge between different voltage domains in mixed-signal systems, providing robust buffering for signals transitioning between 3.3 V and other low-voltage logic levels.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MC74LVX240DTR2G or MC74LVX240MTCX. Verify that substitute parts maintain the same three-state functionality and inverting logic. Ensure the replacement package matches the board footprint exactly, particularly regarding width and pitch specifications.
