Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape/reel specifications. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single 3-to-8 line decoder is required within the LCX logic family constraints. Confirm that the 16-SOIC package dimensions fit the target PCB layout. Verify that the operating voltage requirements align with the 2 V to 3.6 V specification and that the industrial temperature range meets environmental conditions.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the broader 74LCX138 series manufactured by onsemi. Variants such as the 74LCX138BQX offer alternative packaging options like DQFN. The MX suffix specifically denotes the SOIC-16 surface mount package format, distinguishing it from other physical form factors available within the same logical function family.
