Procurement Notes

Verify the specific package suffix against the datasheet ordering codes to ensure correct physical dimensions and pinout compatibility. Confirm that the component meets RoHS standards if required by your manufacturing process. Check for lead-free packaging compliance per JEDEC J-STD-020B specifications. Ensure proper handling procedures are followed due to moisture sensitivity levels associated with surface-mount packages.

Selection Notes

Select this component when designing systems that require bidirectional data transfer between buses operating at different voltage levels. It is suitable for applications needing 5V tolerance on both input and output sides while powered by lower voltages. Consider its propagation delay and drive current capabilities to ensure signal integrity in high-speed digital designs.

Part Context

This device belongs to the LCX family of low-voltage CMOS logic devices. It is functionally similar to other octal bus transceivers but distinguished by its specific 5V tolerance characteristics and low-voltage operation range. The 'WMX' designation indicates a 20-lead SOIC package supplied in tape and reel format.
