Procurement Notes

Verify the specific suffix against the official datasheet to confirm package type and tape-and-reel specifications. Ensure the component matches the required operating temperature range and electrical characteristics for your design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing circuits that require buffering signals between 2V and 3.6V logic domains while maintaining compatibility with 5V interfaces. Consider the SOIC-14 package constraints and thermal dissipation requirements. Evaluate propagation delay and output drive strength against system timing budgets.

Part Context

This component belongs to the 74LCX series of low-voltage CMOS logic devices. It serves as a buffer solution for applications needing signal isolation or amplification. The series is designed for battery-powered devices due to its low static power consumption and wide operating voltage range.

Replacement Considerations

Check for pin-compatible alternatives from other manufacturers such as Toshiba or Texas Instruments. Verify that substitute parts maintain the same 5V tolerance and three-state functionality. Ensure the replacement offers equivalent propagation delays and output current capabilities.
