MC74ACT240DWR2G

Overview

The MC74ACT240DWR2G is an octal buffer and line driver manufactured by onsemi, belonging to the 74ACT logic series. It features eight inverting outputs with three-state capability, housed in a 20-SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides high drive currents of -24 mA for low-level output and 24 mA for high-level output. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent inverting buffer channels
• Three-state output control allowing bus line isolation
• High current drive capability suitable for direct interface with CMOS, NMOS, and TTL loads

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance during procurement. Confirm the package type matches the 20-SOIC requirement. Ensure the supply voltage aligns with the 4.5V to 5.5V operational range. Check for moisture sensitivity handling requirements if storage conditions are not controlled.

Selection Notes

Select this component when an octal inverting buffer with three-state functionality is required at 5V logic levels. The ACT series offers faster propagation delays compared to standard HC or HCT families. Ensure the application demands the specified 24mA drive strength for reliable signal integrity across the bus lines.

Part Context

This part belongs to the 74ACT family of high-speed CMOS logic devices produced by onsemi. It serves as a digital buffer designed for high-performance applications requiring fast switching speeds. The device integrates eight input-output pairs into a single integrated circuit package for space-efficient designs.

Replacement Considerations

Direct replacement options include other 74ACT240 variants from different manufacturers that maintain the same pinout and electrical specifications. Verify compatibility regarding package dimensions and thermal characteristics before substitution.
