Procurement Notes

Verify the specific suffix 'WM' against official Fairchild documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with 5V tolerant interfaces if used in mixed-voltage systems. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Cross-reference pinouts with standard LCX series definitions to prevent integration errors during PCB design.

Selection Notes

Select this component when designing low-voltage (2.3V-3.6V) systems requiring octal buffering with three-state control. It is suitable for applications needing 5V tolerance on both inputs and outputs. Consider its EMI reduction features for noise-sensitive designs. Verify that the required propagation delay and output drive current meet system timing constraints before finalizing the selection.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices manufactured by Fairchild Semiconductor. The LCX series is characterized by its ability to interface between 2.5V/3.3V logic domains and 5V environments. As an octal buffer, it provides eight independent channels, making it efficient for parallel data bus management in microprocessor and memory systems.

Replacement Considerations

Check for direct equivalents such as the 74LCX244MTCX or other LCX-series buffers from ON Semiconductor or Fairchild. Ensure functional parity regarding voltage ranges, output states, and package dimensions. Verify that any substitute maintains the same 5V tolerance and EMI characteristics.
