Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '112' against official Nexperia documentation to confirm package type and tape/reel specifications. Ensure compatibility with RoHS directives and REACH regulations as stated in the datasheet. Confirm availability status directly with authorized distributors, as production lifecycles may change. Cross-reference the ordering code with the manufacturer's current product database to avoid obsolete part substitutions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an 8-bit buffer with three-state capability is required for bus applications. The wide supply voltage range supports both 3.3 V and 5 V logic systems. Overvoltage tolerant inputs simplify interfacing between different voltage domains without additional level shifting components. Verify that the TSSOP-20 or SO package fits the PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC family of high-speed CMOS logic devices. It is functionally similar to other octal buffers like the 74AHCT244 but utilizes CMOS input levels rather than TTL levels. The device serves as a fundamental building block for digital signal routing and isolation in complex electronic systems requiring reliable data transmission.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives such as the 74AHC244D,118 if the '112' suffix indicates a specific packaging variant no longer available. Ensure any substitute maintains the same 3-state output configuration and overvoltage tolerance characteristics.
