74LCX760WM

Overview

The Fairchild Semiconductor 74LCX760WM is an octal buffer and line driver belonging to the LCX logic family. It features non-inverting logic with open-drain outputs, designed for low-voltage applications operating between 2V and 3.6V. The device provides high drive capability with a low-level output current of 24mA and maintains low static power consumption at 10uA. It is housed in a 20-pin SOIC package and supports surface mount installation. The component operates within a temperature range of -40°C to +85°C.

Feature Summary

• Octal buffering architecture providing eight independent non-inverting channels
• Open-drain output configuration suitable for bus-oriented systems
• Low voltage CMOS technology ensuring minimal static power dissipation

Applications

• Bus-oriented memory and signal driving
• Clock distribution and buffering
• High noise immunity I/O interfaces

Procurement Notes

Verify the manufacturer status carefully as this component may be obsolete or end-of-life. Confirm the specific suffix 'WM' matches the required SOIC-20 package variant from official onsemi or Fairchild documentation. Ensure compatibility with existing PCB footprints and verify RoHS compliance details through the latest datasheet before procurement planning.

Selection Notes

Select this part when an octal buffer with open-drain outputs is required for low-voltage logic interfacing. The LCX series offers superior speed and noise performance compared to older LVC families while maintaining 5V tolerance. Consider the 24mA sink capability for driving heavy capacitive loads on data buses.

Part Context

The 74LCX760 is part of the broader LCX logic family developed for low-voltage digital applications. This specific model represents the octal variant, distinguishing it from hex or quad buffers. The component bridges legacy 5V system requirements with modern 3.3V and 2.5V logic standards.

Replacement Considerations

Check for equivalents such as the 74LCX760MSA or generic 74LCX760 variants from other manufacturers. Verify pinout compatibility and electrical specifications against the original datasheet to ensure functional equivalence.
