Overview
The MC74LCX240DWR2G is an octal buffer and line driver manufactured by onsemi, belonging to the 74LCX logic series. It features eight inputs and outputs with three-state capability, housed in a 20-SOIC package. The device operates within a supply voltage range of 2V to 5.5V and supports surface-mount installation. It provides inverted output functionality with high noise immunity suitable for low-voltage applications.
Feature Summary
- Octal configuration providing eight independent input-output channels
- Three-state output design enabling bus-oriented communication
- Inverted logic polarity for signal inversion applications
- Wide operating voltage range supporting 2V to 5.5V systems
Applications
- Memory module data buffering
- Clock distribution networks
- Data bus driving in embedded systems
- Portable equipment signal conditioning
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check moisture sensitivity level handling requirements during storage and assembly. Ensure package integrity matches the specified 20-SOIC form factor before integration into production workflows.
Selection Notes
Select this component when designing circuits requiring octal buffering with three-state control. Consider the 2V to 5.5V supply range compatibility with target system voltages. Evaluate the SOIC-20 package constraints against available PCB real estate. Verify that the inverted output characteristic aligns with the logical requirements of the connected downstream components.
Part Context
This part belongs to the 74LCX family of low-voltage CMOS logic devices from onsemi. It serves as a successor to older 74HC and 74HCT series components in modern low-power designs. The device complements other LCX family members like the non-inverting MC74LCX244 for comprehensive bus interface solutions.
Replacement Considerations
Direct replacement options include the MC74LCX240DW without the suffix if lead-free certification is not required. Cross-reference with SN74LVC240 from Texas Instruments for pin-compatible alternatives in mixed-supplier environments.
