Procurement Notes

Verify the specific suffix M96 against the manufacturer's official documentation to confirm packaging configuration and reel specifications. Ensure compatibility with standard SOIC-16 footprints during PCB layout. Cross-reference electrical parameters with the latest datasheet revision to account for any updates in operating conditions or testing standards prior to final procurement decisions.

Selection Notes

Select this component when a dual 4-input multiplexer with tri-state outputs is required in a 5V logic environment. The HCT series ensures TTL-compatible input levels while offering CMOS speed and power advantages. Consider the SOIC-16 package constraints and verify that the operating temperature range meets the application's thermal requirements before integration into the design.

Part Context

This part belongs to the CD74HCT family of high-speed CMOS logic devices from Texas Instruments. The family is characterized by balanced propagation delays and reduced power dissipation relative to older LSTTL technologies. The CD74HCT253 variant specifically addresses multiplexing needs, providing efficient signal path management in complex digital architectures through its dual-channel structure.

Replacement Considerations

Consult the Texas Instruments replacement guide for verified cross-references. Ensure substitute parts maintain identical pinout configurations and electrical characteristics. Verify that alternative components support the same SOIC-16 package and meet the required 4.5V to 5.5V operating voltage range without compromising signal integrity.
