Latches Procurement Notes

Verify the specific suffix '118' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the AEC-Q100 qualification status meets the specific reliability standards mandated by the target automotive or industrial application environment before finalizing procurement orders.

Latches Selection Notes

Select this component when an octal latch with tri-state capability is required for 5V logic systems. Ensure the design utilizes HCT input levels for direct compatibility with Low-power Schottky TTL sources. Verify that the SOIC-20 package dimensions fit the available PCB footprint constraints and that the thermal characteristics are suitable for the intended operating environment.

Latches Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices produced by Nexperia. The series is engineered to provide pin-to-pin compatibility with legacy Low-power Schottky TTL circuits while offering improved speed and lower power consumption typical of modern CMOS technology. The Q100 designation indicates adherence to automotive quality standards.

Latches Replacement Considerations

Direct substitutes include other 74HCT373 variants from manufacturers such as NXP Semiconductors or STMicroelectronics, provided they maintain the same SOIC-20 package and AEC-Q100 qualification. Verify electrical specifications and pinout compatibility before substitution.
