Procurement Notes

Verify component lifecycle status as STMicroelectronics has marked this part as obsolete. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with current design requirements before procurement due to potential supply chain constraints associated with discontinued components.

Selection Notes

Select this component for applications requiring dual 4-channel signal switching with three-state outputs. Verify that the 16-pin SOIC package fits the PCB layout. Ensure operating conditions remain within the specified 2V to 6V supply range and temperature limits for reliable performance in high-speed digital environments.

Part Context

This component belongs to the M74HC series of high-speed CMOS logic devices manufactured by STMicroelectronics. The HC series is known for wide operating voltage ranges and compatibility with standard TTL logic levels. The M74HC253 specifically provides dual multiplexing functionality within this established logic family framework.

Replacement Considerations

Direct substitutes include CD74HC174M96 from Texas Instruments. Verify pinout and functional compatibility before replacement. Consider equivalent parts from other manufacturers that match the 16-pin SOIC package and dual 4-channel multiplexer specifications.
