MC74LCX540DWR2

Overview

The MC74LCX540DWR2 is an inverting octal buffer manufactured by onsemi, operating from a 2.3 V to 3.6 V supply. It features eight inputs and three-state outputs in a 20-SOIC package. Key electrical parameters include a high-level output current of -24 mA and a low-level output current of 24 mA. The device draws 10 uA static current and has a maximum operating temperature of +85 C.

Feature Summary

• Provides inverting buffering for digital signals within logic circuits
• Supports flow-through pinout configuration for PCB layout flexibility
• Enables bus holding via three-state output control

Applications

• Memory module data buffering
• Clock signal distribution networks
• General-purpose digital logic interfacing

Procurement Notes

Verify the specific suffix 'DWR2' against official datasheets to confirm the tape-and-reel packaging format. Ensure the voltage range aligns with system requirements, as this component operates strictly between 2.3 V and 3.6 V. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component when inverting functionality is required for octal data paths at low voltages. Compare propagation delay specifications against system timing constraints. Evaluate power consumption metrics relative to other LCX series variants to ensure thermal efficiency meets design goals.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices. It serves as the inverting counterpart to the non-inverting MC74LCX541. The device utilizes advanced CMOS technology to achieve high speed while maintaining low power dissipation in portable and battery-operated applications.

Replacement Considerations

MC74LCX540DWR2G is a verified equivalent variant with identical functional specifications.
